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 σ‐bond metathesis on metal hydrides.Keywords
