Abstract
The coupling reaction is best performed by stirring a mixture of 2 molar equiv of (C2H&NSnC13, 1 equiv of PtC12, and CsF in dimethylformamide (DMF) containing 2% water under an atmosphere of vinyl chloride. When (C2H6) 4NSnC13 is used in excess, the yield is 97% based on vinyl chloride in 40 hr at 25". When water is omitted from the solvent, the reaction is slightly faster, but side reactions limit the yield of 85-90%. When CsF is ...
