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 ( H, C, Si NMR, IR, sc-XRD) of heteroleptic metallasilylenes L (Cl)MSiL (M=Al 1, Ga 2, L =HC[C(Me)NDipp] , Dipp=2,6- Pr C H ; L =PhC(N Bu) ). Their electroni...

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