Hydrazides of carboxylates

Hydrazides of carboxylic acids can be prepared by the imidazolide method in a similar manner as amides. 2 These syntheses are also conveniently carried out as one-pot reactions (room temperature, 12 h) ... 

Amides and hydrazides of carboxylic acids have been also used successfully by other groups to stabilize penta- and hexacoordinated silicon. The compounds 119 [265], 120 [266], and 79 [206] serve as examples.
