We report on reactions 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 ) with CO 2 , N 2 O, and Me 3 SiN 3 , yielding the corresponding carbonate complexes L 1 (Cl)MOSi(CO 3 ‐κ 2 O,O−)L 2 (M=Al 3 , Ga 4 ), silanoic esters L 1 (Cl)MOSi(O)L 2 (M=Al 5 , Ga 6 ), and silaimine L 1 (Cl)GaSi(NSiMe 3 )L 2 ( 8 ), whereas {L 2 Si[N(SiMe 3 )Al(Cl)C(Me)NDipp][CHC(Me)N(Dipp)]} 7 was formed by C−C bond cleavage of the L 1 ligand. Compounds 3 – 8 were characterized by NMR ( 1 H, 13 C) and IR spectroscopy, elemental analysis and single crystal X‐ray diffraction.
