Summary
-
1.
The thermal decomposition of (C6H5 3Al, (C4H5Ga, (C6H5)3In, (C6H5)3 Tl in C14-labeled benzene solution is accompanied by the exchange of their phenyl radicals with the solvent. Triphenylaluminum shows the greatest ability to exchange. Triphenylgallium exchanges with benzene with much greater difficulty than does triphenylaluminum, and the ability to exchange increases in the order (C6H5Ga, (C6H5)3In, (C6H5)3Tl.
-
2.
The exchange reaction is not observed in the photodecomposition of the organometallic compounds [(C6H5In].
-
3.
The phenyl radicals of the organometallic compounds react with benzene to yield biphenyl.
