photochromic compounds producing black color 
  I am interested in the synthesis of photochromic compounds especially showing black color upon UV light irradiation. I know that some colorless spiropyrans turn into purple merocyanine, diarylethenes changes their color to red or yellow or blue depending on the structure, fulgides to red or blue. Are there any photochromic... more »

use of the term "parts" in patent docs 
  I'm reading through some patents where reagent amounts are given in "parts". I don't know what this means. I could guess that it means weight percents or eqs. Could someone here tell me?

Getting rid of Cyanogen Bromide 
  Hello All, I have some left-over cyanogen bromide from a cleavage reaction of a protein and I would like to react it to something less dangerous (preferably inert). Does anyone have any suggestions? James

advice sought on LAH 
  ...I don't know where you learned to do synthesis, but feeding HPLC-grade THF into your still is an egregious waste of money. Not necessary.

proton NMR 
  ...see:[link]). ...Hey. I'm having a lot of the same questions as you. Have you found the answers to them. I don't think I got the cyclopentene ring hint. Also, the overlapping triplets - since D and E are in different electronic states, does that mean they split eachother. In which case... more »

Chlorination of Acid 
  Dear All, I was going through an MSc thesis where I read that the chlorination of carboxylic acid was possible in the presence of SOCl2 under anhydrous conditions. The reaction will replace the OH group with Cl group. I was wondering whether it was feasable for phosphoric acid as well? If anyone has the knowledge of such an idea, then please share... more »

proton NMR 
  I am having trouble understanding the H NMR for 5-norbornene-2,3- dicarboxylic anhydride (to see it, please see: [link]). To begin with, I don't understand why H's D and E are labelled as non- identical hydrogens, when you only see one peak for D/E on the... more »
