, p. 654 - 658 (2007/10/02)
The conditions for the isomerization of N-carbodiimides to N-alkylidene-N'-acylureas were investigated.In the reaction of N-carbodiimides with alcohols, phenols, thiophenols, and imines fragmentation of the carbodiimides occurs with the formation of 1-alkoxy-, 1-aryloxy-, 1-arylthio-, and 1-alkylideneaminoalkyl isocyanates and amides.The products from the reaction with water and with tert-butylamine are the amide, ketone, and N-alkylimine.
THERMAL REARRANGEMENT OF DIALKYLIDENEUREAS INTO α-(ALKYLIDENEAMINO)ALKYL ISOCYANATES
Gorbatenko, V. I.,Mel'nichenko, N. V.,Samarai, L. I.
, p. 1064 - 1068 (2007/10/02)
The thermal rearrangement of bisalkylideneureas to α-(alkylideneamino)alkyl isocyanates was studied.Its limits and the relationships governing it were determined.The mechanism of rearrangement is discussed on the basis of the kinetic measurements.
PSEUDOHALOGEN CHARACTER OF THE HETEROCUMULENE GROUP IN GEM-DI(HETEROCUMULENO)ALKANES

In the reactions of gem-di(heterocumuleno)alkanes with triphenylphosphoranediylaminotrimethylsilane or N-(trimethylsilyl)diphenylketimine one heterocumulene group (isocyanate or carbodiimide) exhibits pseudohalogen characteristics.A new rearrangement with migration of the N=C(C6H5)2 group was discovered in the azaallyl triad C=N-C.
