Hydrosilylation of 1,4-bis(trimethylsily)-1,3-butadiyne with platinum and rhodium catalyst proceeded stepwise to give first 2-silyl-1,4-bis(trimethylsilyl)-1-buten-3-ynes and then 1,3-disilyl-1,4-bis(trimethylsilyl)-1,2-butadienes in high yields.
The Rh and Ni catalyzed hydrosilylation of butadiynes to chiral allenes in the presence of chiral phosphine ligands is described. For the first time an enantiomeric excess up to 27% was achieved using [Rh(COD)Cl]2/(−)-PPM and up to 11% using NiCl2[(−)-DIOP].
