Abstract

C-C activation of unactivated alkanes on a silica-supported neopentyl neopentylidene Tav complex [Eq. (1)] affords the alkane cross-metathesis products tBuCH2R and an alkane-metathesis catalyst. Since the activity and product distributions are similar to those obtained with a silica-supported TaIII hydride, these results are a first step in understanding alkane ο-bond metathesis on metal hydrides.
