Novel generation of azomethine imines from α-silylnitrosamines by 1,4- silatropic shift and their cycloaddition

Novel and facile generation of azomethine imines from α- silylnitrosamines and subsequent cycloaddition with dipolarophiles leading to a variety of pyrazole derivatives have been developed. The key to the reaction is a 1,4-silatropic shift caused by stron

Benzoyl phenyl 1-methylpyrazoles. Synthesis, characterization, and spectra

The synthesis and unequivocal characterization of all six isomers of benzoyl phenyl 1-methylpyrazole (2) are described.The isomer of 2 isolated as one of the products of the reaction of 1,1-dimethyl-1-phenacylhydrazinium bromide (1) with base was shown to be only previously reported isomer, 5-benzoyl-3-phenyl-1-methylpyrazole (2b).
