Popis: | Reaction of potassium trithiocarbonate with 1,4-dichloro-, 1,4-bis(tosyloxy)- or 1,4-dibromo-2-butyne (1a-c) affords 4-vinylidene-1,3-dithiolane-2-thione (2) in excellent yields. The trithiocarbonate 2 is desulfurized with 1,3-dimethyl-2-phenyl-1,3,2-diazaphospholidine (3) to give butatriene (4) under very mild conditions |
