Yv. Badeev et al., REACTIONS OF SULFITES WITH SECONDARY-AMINES - 1 - DIPHENYL AND ALKYL PHENYL SULFITES, Russian chemical bulletin, 47(7), 1998, pp. 1356-1358
The interaction of diethylamine and morpholine with diphenyl, methyl p
henyl, ethyl phenyl, and isopropyl phenyl sulfites was studied. It was
established that two reactions, substitution and alkylation, can occu
r in parallel. Diphenyl sulfites react with amines to give only substi
tution products, while other sulfites react with substitution at the s
ulfur atom and with alkylation of the amines.
