Abstract
The gas-phase pyrolysis of triethylgallane, triisopropylgallane, triis obutylgallane, tri-tert-butylgallane, and trimethylgallane have been s tudied using infrared laser-powered homogeneous pyrolysis (IR LPHP). I dentification of products by infrared and NMR spectroscopies confirmed that the predominant reaction pathway is beta-hydride elimination, bu t that the pyrolysis proceeds at a significantly lower temperature in case of triisopropylgallane, triisobutylgallane tri-tert-butylgallne t han that of triethylgallane. Moreover the beta-hydride elimination rou te is not available in the pyrolysis of trimethylgallane. (C) 1997 Els evier Science B.V.
