The allylboration of alkenes with allyldibromoborane is described. Utilizing an improved methodology for the synthesis of allyldibromoborane, 1,3-dienes, styrene, and even isolated alkenes could be carbometalated in high yield regio- and stereospecifically at 0 °C. This high reactivity of allyldibromoborane significantly expands the scope of carbometalations of alkenes.
