Imines, enamines and oximes

Imines, enamines and oximes were discussed. Imines were formed by the action of catalytic scandium or lanthanide triflates on a mixture of acetals and primary amines in toluene with molecular sieves in 41-96% yields. Aldehydes and ketones reacted with primary amines to give imines in 80-97% yields by using microwave irradiation with envirocat EPZG(R) as a catalyst under solvent free conditions. Results showed that oximes were conveniently converted into nitroalkanes using oxone in acetonitrile, buffered at pH 7.5.
