Efficient Conditions for the Palladium(II) Mediated Coupling of Organostannanes: The Synthesis of 1,3-Dienes, 1,4-Dienes, 1,3-Diynes and Biphenyls

Article abstract of DOI:10.1055/s-1997-5768

Convenient conditions are described for the preparation of 1,3-dienes by vinylstannane homocoupling using palladium(II)-catalysis with oxygen (or air) for Pd(0)/Pd(II) reoxidation; related homo-couplings, and cross-coupling reactions with allylstannane, are used to obtain 1,3-diynes, biaryls and 1,4-dienes.
