Abstract

An AuC bond order of 0.8 characterizes the pentaauriomethyl cation 1, so that the central carbon atom cannot be regarded as hypervalent. Compound 1 is formed from CH₂[B(OMe)₂]₂ and [Ph₃PAuCl] in the presence of CsF as BF 4⊖ salt in 84% yield. The trigonal‐bipyramidal coordination of the carbon center is slightly distorted. This may be due to a reduction in energy upon lowering the symmetry or to ligand–ligand repulsion or packing effects. (Figure Presented.)
