Abstract

Abstract: Reactions of alkenes with dichloroborane ethyl etherate (BHCIyEE) and alkynes with dichloroborane tetrahydrofuranate (BHCITTHF) and BHC12. EE were investigated in detail. The hydroboration of alkenes with BHCIz-EE in ether or pentane is slow and incomplete. However, the reaction goes to completion when neat reagents are allowed to react, but the resulting product is predominantly the dialkylchloroborane (RzBCI) and not ...
