Dinitrophenyl (DNP)-amino acids have been calorimetrically determined by making use of the red color formed by their reaction with cyanide in dimethy~suifoxide or dimethyiacetamide. The extinction coefficients are over 20,000, making this method more sensitive than previous methods which have used

β¦ Synopsis
A review of the chemical literature reveals a number of addition reactions to the nitroso functional group which appear analogous in many respects to those observed for carbonyl compounds.
1 It is also recognized that nitroso compounds are excellent acceptors of electrons from anionic species to yield corresponding radical anions. 2

We have found that substituent groups and solvents may have striking effects on the rates of bimolecular reactions involving nucleophiles and photoexcited nitroaromatic compounds. As representative cases, data on reactions of cyanide ion and 4-nitroanisole, l-nitronaphtbalene. and 4-methoxy-1-nitron
