A Facile Route to Group 13 Difluorodiorganometalates:

A facile synthesis utilizing tetra-n-butylammonium hydrogen difluoride and Group 13 alkyl compounds leads to the soluble salts 1 - 4. Compound 1 is the smallest difluoro-diorganoaluminate so far characterized. The corresponding gallium and indium derivatives 3 and 4 are not sensitive to moisture.
