amidation between esters and amines or hydrazines is described. This strategy was tolerant for a wide scope of substrates, affording a series of amides (or hydrazides) in good to excellent yields (60–96%) under simple conditions. The approach was also used to synthesize the pharmaceutically relevant antidepressant moclobemide in 85% yield. An efficient NHC-catalyzed amidation between esters and amines or

Certain five-membered heterocyclic derivatives of N'- substi uted-N,N'-diacylhydrazines are insecticidally active comp sunds and may be used, optionally in compositions cont1 ning agronomically acceptable diluent or carrier, to con at insects, particularly those from the order Lepi- dop t ra.
