资源简介：
Complexes [PhBPPh3]RuH(η3-H2SiRR′) (R,R′
= Me,Ph, 1a; RR′ = Ph2, 1b) react with XylNC
(Xyl = 2,6-dimethylphenyl) to form Fischer carbene complexes [PhBPPh3]Ru(H)[C(H)(N(Xyl)(η2-H–SiRR′))] (2a,b) that feature
a γ-agostic Si–H bond. The ruthenium isocyanide complexes
[PhBPPh3]Ru(H)(CNXyl)(η2-HSiHRR′)
(6a,b) are not intermediates as they do
not convert to 2a,b. Experimental and theoretical
investigations indicate that XylNC is activated by initial coordination
to the silicon center in 1a,b, followed
by 1,1-insertion into an Si–H bond of the coordinated silane
and then rearrangement to 2a,b.
