NOVEL SYNTHESIS OF INTERNAL ALKENYLDIALKYLBORANE BY THE REACTION OF 1-HALO-1-ALKENYLDIALKYLBORANE WITH GRIGNARD REAGENT.

Arase,Hoshi,Masuda

, p. 209 - 213 (2007/10/02)

To synthesize internal alkenyldialkylboranes, coupling reactions were carried out by using 1-halo-1-alkenyldialkylboranes and Grignard reagents. Hydrogen peroxide oxidation and protonolysis with acetic acid of the reaction product revealed that internal (E)-alkenyldialkylborane was formed in 60-90% yield.
