The mutual exchange of methyl groups of ethane molecules is catalyzed by a silica-supported tantalum hydride surface complex (see the schematic representation of the transition states). This process, which resembles degenerate olefin metathesis, is five times faster than the productive alkane metathesis.
乙烷分子甲基的相互交换由二氧化硅负载的氢化钽表面络合物催化（见过渡态的示意图）。这个类似于简并烯烃复分解的过程比有效的烷烃复分解快五倍。
