One up in limiting reactivity : The monosubstitution of multifunctional molecules is a general problem in synthetic chemistry. The catalyst [Cp*(P i Pr 3 )(H) 2 RuSi(H)Ph⋅Et 2 O][B(C 6 F 5 ) 4 ] (Cp*=η 5 ‐C 5 Me 5 ) can be used for the alkylation of phenylsilane PhSiH 3 with simple olefins. The reaction stops at the monoalkylation level to give PhSi(Alk)H 2 (see scheme; R=H, C 6 H 5 , C 4 H 9 ).
