Abstract Aldehydes and ketones containing no α-hydrogen atoms yield the corresponding dialkylidene sulfamides both by reacting with sulfamide in presence of a proton acid or of SOCl 2 and by reacting with bis (trichlorphosphazo)-sulfone. The dialkylidene sulfamides of ketones also were obtained by treating ketone imines with sulfamide. Chloral did not react with sulfamide in this way but yielded 3, 7-bis-(trichloromethyl)-perhydro-1, 5, 2, 4, 6, 8- ...
