Synthesis and Structures of Metal‐Containing Eight‐Membered N — S — O Heterocycles Racemic N ‐alkylsulfinamides 1a, b react with aluminium, gallium, and indium alkyls 2a — d to form puckered eight‐membered NSO‐complexes [Me 2 AlN(CF 3 ) 2 C 6 H 3 S( t Bu)O] 2 ( 3a ), [Me 2 AlN‐(Ph)S( t Bu)O] 2 ( 3b ), [Me 2 GaN(CF 3 ) 2 C 6 H 3 S( t Bu)O] 2 ( 3c ), [(Me 3 ‐ SiCH 2 ) 2 GaN(CF 3 ) 2 C 6 H 3 S( t Bu)O] 2 ( 3d ), [(Me 3 SiCH 2 ) 2 InN(Ph)S‐ ( t Bu)O] 2 ( 3e ), and [(Me 3 SiCH 2 ) 2 InN(CF 3 ) 2 C 6 H 3 S( t Bu)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 ).
