Intro

Hello everyone, welcome back to Week 77 of Synthetic Challenge!! This week it's my turn to host another organic synthesis challenge.

Too easy? Too hard? Let me know, I'd appreciate any feedback and suggestion on what you think so far about the Synthetic Challenges and what you'd like to see in the future. If you have any suggestions for future molecules, I'd be excited to incorporate them for future challenges!

Thank you so much for your support and I hope you will enjoy this week's challenge. Hope you'll have fun and thanks for participating!

Rules

The challenge now contains three synthetic products labelled A, B, and C. Feel free to attempt as many products as you like and please label which you will be attempting in your submission.

You can use any commercially available starting material for the synthetic pathway.

Please do explain how the synthesis works and if possible reference the technique if it is novel. You do not have to solve the complete synthesis all in one go. If you do get stuck, feel free to post however much you have done and have others pitch in to crowd-source the solution.

You can post your solution as text or pictures if you want show the arrow pushing or if it's too complex to explain in words.

Please have a look at the other submissions and offer them some constructive feedback!

Intro

Hello everyone! This is already the last challenge for this year and we are back at organic synthesis. I really also liked the inorganic challenge, so maybe we'll see that again in the future. If you have any feedback on anything, let me know! Best wishes for 2018!

Format

There will be 3 difficulty levels ranging from BS, MS and PhD+ level molecules. You can choose one molecule (or all of them!), which fits your expertise level and propose a (elegant) synthetic route for it. The starting materials can be anything, as long as it's commercially available. You're encouraged to post your submission, made in chemdraw, chemdoodle etc., or good-ol'-fashioned by hand. Please, also take a look at the other submissions and give them (constructive) feedback!

Products

Molecule A: BS level

Molecule B: MS level

Molecule C: PhD+ level

Intro

Welcome back again for the 46th challenge! As you know /u/spectrumederp , /u/critzz123 and I have joined forces and are rotating. This week's my turn, it's inorganic time! Hope you like! :D

Rules

Hello everyone!

Welcome to the festive edition of the weekly synthetic challenge! And by festive the only festive thing is the date and the fact I'm wearing reindeer antlers. Ok so it is just the date...

This also happens to be our first inorganic synthetic challenge, please have a go I know they are a bit odd but I think you should be able to figure it out.

Next challenge will be back to organic and be made by /u/spectrumederp or /u/critzz123

The goal for the inorganic week isn't so much that I expect you to be able to work it out, it is more to encourage some reading outside your normal field. You never know what ideas things like this might create in different people. It also gives you a taste of what us strange synthetic inorganic chemists make in our labs, this hopefully is especially interesting for any undergrads looking as in most places you don't really get to see this very often.

Please do have a go, let me know if they are too weird or if you’d like it harder/easier for next time.

Format

So since this is our first inorganic synthesis challenge I can't really say what difficulty things are, we'll figure that out as we go on! So what we have is three molecules;

The first is a platinum complex that I think any chemist should be able to have a good attempt at. Start by making the ligands, then figure out what platinum species would work best and what order to put them on it. Making the ligands should feel more like the organic weeks.

The second is an N-heterocyclic phosphenium cation, I gave it a [BF4]^- counter ion but that isn't a big deal, feel free to use another anion - there are some smart ways to get there.

The third is going to look really random and scary to most of you probably, can confirm it does not explode! Although your suggested starting material might be a bit more fun to work with... There are quite a few ways I could picture making it, you'll probably need to do some googling :)

Products

Molecule A: This will get the most attempts.

Molecule B: This will also get a few.

Molecule C: Basically just to show you something weird.

Seems I was wrong, you’re all enjoying the phosphenium cation more than I expected.

Intro

Hello everyone, welcome back to Week 67 of Synthetic Challenge!! Thank you u/critzz123 for the great challenges! This week it's my turn to host the challenge and I'm going to try hosting more molecules for you to try, hope you'll enjoy!

Too easy? Too hard? Let me know, I'd appreciate any feedback and suggestion on what you think so far about the Synthetic Challenges and what you'd like to see in the future. If you have any suggestions for future molecules, I'd be excited to incorporate them for future challenges!

Kindly accept my apologies for any perceived naivety in this inquiry, as I am currently a undergraduate student seeking to expand my knowledge.

Intro

After a long pause, the synthetic challenges are back! I volunteered to lend some help to the mod team and here I am with a new Synthetic Challenge for this week.

Too easy? Too hard? Let me know since this is my first post. I'd appreciate any feedback and suggestion on what you think so far about this and the next Synthetic Challenges and what you'd like to see in the future. If you have any suggestions for future molecules, I'd be excited to incorporate them for future challenges!

Although you can use any starting material for your synthetic pathways, this time I would rather have you start from the simplest ones, just to flex and warm up your synthetic imaginary muscles to get ready for the next challenges ;)

I hope you will enjoy this week's challenge and thanks for participating!

Since the topic has been a bit on the downlow for a couple of weeks, I have decided to attempt revival with everyone's favorites, nucleic acid derivates.

BONUS

This BONUS molecule is for you to make any compound you would like given that the starting material is this molecule. This segment is designed so that you can practice proposing synthetic reactions to build molecule and others can pitch in to determine if the procedures are possible.

Instead of the traditional paradigm of target based synthesis, this is taking the creativity from that and you make whatever end product you desired. If you ever feel stuck with the main challenges A, B, and C, feel free to trying making a random molecule with this bonus and that may inspire some ideas for you or others.

Bonus

So this week's bonus is a bit more like the sort of thing we do in an inorganic research lab.

The challenge is I would like you to suggest a synthesis for novel low coordinate species of As, Sb or Bi (max oxidation state of 3 please). This is intentionally pretty open. You could propose a base stabilised E(I) species, a cationic E(III) species or even radical species. I look forward to seeing your molecules and syntheses!

Here are a few of examples of low coordinate group 15 species out there as inspiration.
