摘要
Cp*2NdCH(SiMe(3))(2) efficiently catalyzes hydrosilation of 1,3-, 1,5-, and 1,6-dienes under mild conditions with unusual selectivities as compared with later transition metal-catalyzed reactions; hydrosilation of isoprene affords mainly (E)-, not (Z)-, allylsilane. On the other hand, hydrosilation of 1,5- and 1,6-dienes proceeds through intramolecular C-C bond formation to give (silylmethyl)cyclopentanes.
