Selective [2+1+1] Fragmentation of P(4) by heteroleptic Metallasilylenes

Small‐molecule activation by low‐valent main‐group element compounds is of general interest. We here report the synthesis and characterization ((1)H, (13)C, (29)Si NMR, IR, sc‐XRD) of heteroleptic metallasilylenes L(1)(Cl)MSiL(2) (M=Al 1, Ga 2, L(1)=HC[C(Me)NDipp](2), Dipp=2,6‐( i )Pr(2)C(6)H(3); L(...

Sumario:Small‐molecule activation by low‐valent main‐group element compounds is of general interest. We here report the synthesis and characterization ((1)H, (13)C, (29)Si NMR, IR, sc‐XRD) of heteroleptic metallasilylenes L(1)(Cl)MSiL(2) (M=Al 1, Ga 2, L(1)=HC[C(Me)NDipp](2), Dipp=2,6‐( i )Pr(2)C(6)H(3); L(2)=PhC(N( t )Bu)(2)). Their electronic nature was analyzed by quantum chemical computations, while their promising potential in small‐molecule activation was demonstrated in reactions with P(4), which occurred with unprecedented [2+1+1] fragmentation of the P(4) tetrahedron and formation of L(1)(Cl)MPSi(L(2))PPSi(L(2))PM(Cl)L(1) (M=Al 3, Ga 4).
