Catalyst-free dehydrocoupling of amines, alcohols, and thiols with pinacol borane and 9-borabicyclononane (9-BBN)
TL;DR: The dehydrocoupling of pinacol borane and 9-borabicyclononane with a variety of amines, alcohols and thiols can be achieved under mild conditions without catalyst.
Journal ArticleDOI
Dramatic effect of Lewis acids on the rhodium-catalyzed hydroboration of olefins.
TL;DR: Preliminary mechanistic studies suggest that the B(C(6)F(5) needs to be present throughout the course of the reaction, not just at the initiation stage, and implicate this species, along with THF, in the heterolytic cleavage of the B-H bond of HBPin.
