A novel butatriene synthesis

A novel butatriene synthesis. Herges, Rainer; Hoock, Christoph (Inst. Org. Chem., Univ. Erlangen-Nuernberg, Erlangen D-8520, Germany). Synthesis, (12), 1151-2 (English) 1991. CODEN: SYNTBF. ISSN: 0039-7881. 821-10-3 and 2219-66-1 are also in the experiment. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Reaction of potassium trithiocarbonate with 1,4-dichloro-, 1,4-bis(tosyloxy)- or 1,4-dibromo-2-butyne in CH2Cl2 contg. a catalytic amt. of 18-crown-6 afforded 75% 4-vinylidene-1,3-dithiolane-2-thione (I). The trithiocarbonate I is desulfurized with 1,2-dimethyl-2-phenyl-1,3,2-diazaphospholidine to give 85-90% butatriene under very mild conditions. .
