N-CARBODIIMIDES. II. REACTIONS WITH CARBOXYLIC ACIDS AND O,O-DIALKYL HYDROGEN DITHIOPHOSPHATES
Vovk, M. V.,Dorokhov, V. I.,Samarai, L. I.
, p. 1113 - 1116 (2007/10/02)
The reaction of N-carbodiimides with carboxylic acids and O,O-dialkyl hydrogen dithiophosphates is accompanied by fragmentation of the carbodiimide molecule and leads to the formation of N-substituted amides and 1-(acyloxy)alkyl isocyana
