Synthesis and Structures of Metal-Containing Eight-Membered N - S - O HeterocyclesRacemic N-alkylsulfinamides 1a, b react with aluminium, gallium, and indium alkyls 2a - d to form puckered eight-membered NSO-complexes [Me2AlN(CF3)2C6H3S(tBu)O]2 (3a), [Me2AlN-(Ph)S(tBu)O]2 (3b), [Me2GaN(CF3)2C6H3S(tBu)O]2 (3c), [(Me3- SiCH2)2GaN(CF3)2C6H3S(tBu)O]2 (3d), [(Me3SiCH2)2InN(Ph)S- (tBu)O]2 (3e), and [(Me3SiCH2)2InN(CF3)2C6H3S(tBu)O]2 (3f). Compounds 3a, c, d crystallize in the triclinic space group P¯1. A comparision of the X-ray structures of 3a, c, d reveals that the sulfur atoms in one molecule of 3d have either (R,R) or (S,S) configuration (Z = 2). In the case of less bulky ligands at the metal atoms (3a, c) both configurations at the sulfur atoms (R,S) are present in one molecule (Z = 1).
