  Dehydrogenative Oligomerization of PhSiH₃ Catalyzed by (1-Me-Indenyl)Ni(PR₃)(Me)

  摘要：

  The complexes (1-Me-Ind)Ni(PR3)Me (Ind = indenyl; R = Ph, 1; Cy, 2; Me, 3) can act as single-component precatalysts for the dehydrogenative oligomerization of PhSiH3 to (PhSiH)(n) with M-w up to 1.6 x 10(3) in the case of 3. The catalytic Si-Si bond formation is initiated by a second-order, concerted reaction between the Ni-Me precursor and PhSiH3 which releases CH4. Kinetic studies of this Si-H bond activation step gave the following activation parameters for the reaction of 3 with PhSiH3: DeltaH(double dagger) = 10.7 +/- 0.7 kcal-mol(-1); DeltaS(double dagger) = -42 +/- 2 eu;k(H)/k(D) (for reaction with PhSiD3 at 313 K) = 9.8 +/- 0.5. The Ni-SiPhH2 species presumed to form in this reaction was not detected directly, but the presence of 1-SiPhH2-3-Me-Ind in the reaction mixtures, coupled with the fact that Ni(PMe3)(4) is an active precatalyst for the oligomerization of PhSiH3, suggests that the silyl intermediate undergoes a reductive elimination to generate Ni(O) species which might be involved in the catalysis.
