A copper complex has been found to catalyze the borylstannylation of alkenes through
three-component coupling with a diboron and a tin alkoxide, affording vic-borylstannylalkanes of structural diversity in a regio- and stereoselective manner.
The versatility of this borylstannylation has been also demonstrated by employing
allenes, leading to the sole formation of borylstannylated products, which have alkenylborane
and allylstannane units.
