摘要

二氧化硅负载的氢化钽在低温下分别激活环辛烷和CD4的C-H键和C-D键，形成相应的环辛烷和过氘甲基钽表面配合物;这些配合物在分子氧作用下转化为相应的钽烷氧基衍生物，与乙酸反应生成相应的烷基乙酸酯。

Activation and functionalisation of the C–H bonds of methane and higher alkanes by a silica-supported tantalum hydride complex

Silica-supported tantalum hydride activates at low temperature the C–H and the C–D bonds of cyclooctane and CD4, respectively, to form the corresponding cyclooctyl and perdeuteriomethyl-tantalum surface complexes; these complexes are transformed under molecular oxygen into the corresponding tantalum-alkoxy derivatives which with acetic acid give rise to the corresponding alkylacetates.
