Abstract

Abstract A convenient approach to the highly reactive allylic dihaloboranes and diallyl (chloro) borane based on exchange reactions between BHal 3 (Hal= Cl, Br) and allylic triorganoboranes (allyl, cinnamyl and 2-methylenecyclobutane derivatives) has been developed. The compounds thus generated readily react with terminal alkenes and acetylenes to form the corresponding cis-1, 2-allylboration products. These products were ...
