Vinylic organoboranes. 13. A convenient stereospecific synthesis of (Z)-1-halo-1-alkenes from 1-alkynes via (E)-1-alkenylborane derivatives with halogens
Stereochemically pure (E)- and (Z)-alk-1-en-1-yl acetates have been easily prepared by acetoxylation of the (Z)- and (E)-alk-1-en-1-ylboronic acids or their esters, respectively, with (diacetoxyiodo)benzene and sodium iodide, in reasonable yields.

Stereo- and regiospecific syntheses to provide conjugated (E,Z)- and (Z,Z)-alkadienes, and arylated (Z)-alkenes in excellent yields via the palladium-catalyzed cross-coupling reactions of (Z)-1-alkenylboronates with 1-bromoalkenes and aryl iodides
