Preparation of (Z)-1,2-dichloroalkenes from terminal alkynes

(Z)-1,2-Dihaloalkenes are thermodynamically disfavoured of the two stereoisomers. This paper reports the synthesis of some (Z)-1,2-dichloroalkene analogues from mucochloric acid. A more versatile approach involved the chloroboration of terminal alkynes to yield corresponding (Z)-chloroboronic acid as a first step. Treatment of the organoboronic acid with potassium hydrogen difluoride followed by tetrabutylammonium trichloride gave (Z)-1,2- dichloroalkenes in moderate to good yields in a stereospecific manner.
