Abstract
[Rh(cod)Cl]2-catalysed hydrosilylation of hex-1-yne with Et3SiH in EtOH or DMF is highly selective for the formation of (Z)-vinylsilane, whereas [Rh(cod)Cl]2-PPh3 in MeCN or PrnCN is highly selective for the formation of (E)-vinylsilane; the active species for cis addition has been revealed to be RhI cationic complex generated in situ.Keywords
