Synthesis, Structure, and Rearrangement of Chlorobis(2,4,6‐tri‐ tert ‐butylphenyl)gallane The title compound 1 is easily obtained from GaCl 3 and 2 equvialents of supermesityllithium. According to an X‐ray structure analysis one of the supermesityl rings shows a large deviation from planarity. Heating of 1 in vacuo gives mainly two products: an isomer of 1 in which one of the supermesityl groups is bound to Ga by one of its tert ‐butyl groups ( 2 ) and a benzo[ b ]gallolane ( 3 ) formed by elimination of HCl, X‐ray structure analyses and full NMR ( 1 H, 13 C) data are provided for 1 and 2 , MS and characteristic NMR ( 1 H, 13 C) data for 3 .
