研究发现，在催化量的钯或镍络合物存在下，炔基、烯丙基、酰基、烯基和芳基锡烷中的碳-锡键与炔烃、1,3-二烯和1,2-二烯的碳-碳不饱和键加成，得到具有各种官能团的烯基-或烯丙基锡烷。提出的机制是从碳-锡键的氧化加成开始，或形成环钯，然后消除β-锡或与有机锡烷反应。
Carbon–tin bonds in alkynyl-, allyl-, acyl-, alkenyl-, and arylstannanes were found to add to carbon–carbon unsaturated bonds of alkynes, 1,3-dienes and 1,2-dienes in the presence of a catalytic amount of palladium or nickel complexes to give alkenyl- or allylstannanes having various functional groups. Mechanisms are proposed that start with oxidative addition of a carbon–tin bond, or palladacycle formation followed by β-tin elimination or by the reaction with an organostannane.
