摘要：

Condensation of diphenylphosphinylacetohydrazide with aldehydes, ketones, and dibenzoyl yields hydrazones. The hydrazonic fragment of these compounds in the crystalline state exists as the EE'Z " isomer, and in DMSO solution, as a mixture of rotamers stabilized by an intramolecular hydrogen bond. Reaction of diphenylphosphinylacetohydrazide with glyoxal gives the corresponding osazone, while with diethyl diacetyl-succinate a pyrrole derivative is formed. Ethoxymethylenecyanoacetic acid ester reacts with the hydrazide under study exclusively by the ethoxymethylene group.
