Aryl- and (perfluoroaryl)trichlorogermanes ArGeCl3(Ar = C 6H5, 2-FC6H4, 3,5-(CF 3)2C6H3, C6F5, 2,3,5,6-F4C5N) are easily obtained in 60-80% yields from the corresponding tributyl-stannanes and GeCl4 (1:1) at 150 °C in the absence of a solvent. Although the tin-to-germanium transmetalation of C6F5 group is sluggish, it is facilitated by addition of 1-2 mol % AIBN (2,2′-azobis(isobutyronitrile)).

Gold(i)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium salts.
