Laser-powered homogeneous pyrolysis of triisobutylgallane and tri-tert-butylgallane

The gas-phase pyrolysis of tri-tert-butylgallane and triisobutylgallane has been studied using infrared laser-powered homogeneous pyrolysis. Identification of products by infrared and NMR spectroscopies confirmed that the predominant reaction pathway is β-hydride elimination in both cases, but that the pyrolysis proceeds at a significantly lower temperature than that of triethylgallium.
