Abstract

The rate of the reaction, H2+D2 → 2HD, is very rapid at -160 °C on the catalyst Cp′2Th-(CH3)2/dehydroxylated Al2O3, activated in H2+D2 and believed to contain supported Cp′2ThH+(Cp′ = η5-pentamethylcyclopentadienyl). Even at -195 °C, the turnover frequency is greater than 0.1 sec-1 at {Mathematical expression} atm. Strong evidence is adduced that the exchange proceeds by a Rideal-Eley process, i.e. by a four-center transition state involving Th-H+D-D.
