Facile and stereospecific synthesis of 1,1-dihalogenoalk-1-enes from 1-halogenoalk-1-ynes by hydroboration

Masuda, Yuzuru,Suyama, Toshihiro,Murata, Miki,Watanabe, Shinji

, p. 2955 - 2956 (2007/10/03)

1-Halogenoalk-1-ynes upon hydroboration with diakylborane followed by treatment with copper(II) halides in the presence of a small amount of water in polar aprotic solvents give both mixed 1,1-dihalogenoalk-1-enes of defined stereochemistry and single isomers in reasonable yield.
