Synthesis of hindered hydrazones and their reaction with thionyl chloride

Hydrazones 12a-c and ketazines 13a-c were prepared by the reaction of ketones 11a-c with hydrazine hydrate depending on the temperature and the reaction time. Some ketone (aryl)hydrazone derivatives 14a,c,e reacted with thionyl chloride to afford the chlo
