Addition at Double Bonds via Organoborane Intermediates

Some of the most synthetically useful addition reactions of alkynes are with organometallic reagents, and these reactions, which can lead to carbon-carbon bond formation, are discussed in Chapter 8. [Pg.337]

Addition at Double Bonds via Organoborane Intermediates 4.5.1. Hydroboradon [Pg.337]

Borane, BH3, having only six valence electrons on boron, is an avid electron pair acceptor. Pure borane exists as a dimer in which two hydrogens bridge the borons. [Pg.337]

In aprotic solvents that can act as electron pair donors such as ethers, tertiary amines, and sulfides, borane forms Lewis acid-base adducts. [Pg.337]
