摘要

Summary. Acetylenic compounds RC = CH can be converted into acetylenic thioethers by treatment of the sodium or lithium alkynide with diethyl disulphide in liquid ammonia. This constitutes the easiest route to 1-ethylthio- I-alkynes I. Other compounds with “acidic” CH3, CH2 or CH groups can like- wise be alkylthiolated; generally the product containing two geminal ethylthio groups is formed in excess. ... Disulphides RS-SR can be subjected to nucleophilic substitution ; ...
