Abstract
The reductive condensation of trichloromethylarenes with hydrazines can pro ceed without intermediate formation of pyridinium salts and without partici pation of pyridine in the reduction act. Variants of reductive condensation using hydrazines as reducting agents and alpha-chlorobenzylhydrazines and hydrazonoyl chlorides, nitrile imines, or hydrazonoylpyridinium salts as in termediates are considered, alpha-Chlorobenzylhydmzines and hydrazonoyl chl orides are shown to be the most probable intermediates.
