The hydrazone structure was preferred because of the ease with which S,S -dialkylation of N-aryl dithiocarbazates is known to take place and because acid hydrolysis of the product yields 1,3-dithio]sn-2-cne (CCXXIV) and the aryl hydrazine. The hydrazone (CCXXIII, R2=1 3=R.i=1 5 =H, Ri=CfiH5), independently prepared from 2-imino-1,3-dithiolane (CCX X. V ) 374 and phenylhydrazine 254), has the same melting point (94° C) and causes no lowering of the melting point when mixed with the product prepared from N-phenyl dithiocarbazate and 1,2-dibromoethane (m.p. 

Epoxides (372) react with CS2 in the presence of EtsN to give products including the oxathiolanones (380) and oxathiolanethiones (381) <88BCJ921) and l,3-dithiolane-2-thione similarly gives (382) and (383) <91HCA1500). Treatment of the epoxide (384) with KSCN gives the 2-imino-... 

According to the original process of Addor (1962), phospholan is prepared by the reaction of ethylene-1,2-dithiol with cyanogen chloride, followed by the reaction of 2-imino-l,3-dithiolane (103) with diethyl phosphorochloridate. According to his later process (1970), N-(0,0-diethylphosphoryl) dithiocarbamate (104), obtained by the addition reaction of diethyl phosphoryl isothiocyanate and potassium hydrosulilde, is cyclised with ethylene bromide.
