Resumen:
Gem-diborylalkenes have emerged as efficient reagents for selective cross-coupling reactions, reduction approaches and Michael additions. The synthesis of the 1,1-diborylalkenes involves condensation of polyborated compounds with aldehydes or ketones followed by B-O elimination, geminal diboration of 1,1-dihaloalkenes, 1-haloalkenes as well as terminal alkynes, dehydrogenative borylation of alkenes, borylation of alkynylboronates and hydroboration of alkynylboronates. These new set of reactions become general for a wide range of substrates and they can be understood by complementary mechanisms.
