Ylide–Metal Complexes. XII. The Preparation and Properties of Au, Be, Al, Ga, and In Complexes with Dimethylsulfoxonium Methylide

The reaction of dimethylsulfoxonium methylide, (CH3)2+S(O)–\"{C}H2 (L), with (triphenylphosphine)gold chloride, (C6H5)3PAuCl, yields a new bis(dimethylsulfoxonium methylide)gold(I) chloride, [(CH3)2S(O)CH2AuCH2S(O)(CH3)2]Cl. The reaction of the ylide L with BeCl2 yields a new compound of tetrakis(dimethylsulfoxonium methylide)beryllium dichloride, [(CH3)2S(O)CH2]4BeCl2. The reactions of the ylide L with AlCl3, GaCl3, and InCl3 yield new dimeric compounds of μ-chlorobis[tris(dimethylsulfoxonium methylide)metal] pentachloride, [{(CH3)2S(O)CH2}3M–Cl–M{CH2S(O)(CH3)2}3]Cl5 (M: Al, Ga, and In). All complexes are thermally stable.
