铬(VI)二烷基络合物[Cr(NC6H3Pri2-2，6)2(CH2CMe3)2]在室温的烃类和乙醚溶液中容易消除CMe4生成六价亚烷基物种[Cr(NC6H3Pri2-2，6)2)(CMe3)]，该物种可以在强给体分子存在下被捕获，得到第一个稳定的六价铬亚烷配合物[Cr(NC6H3Pri2-2，6)2(CHCMe3(L)](L=四氢呋喃，PMe3)。
The chromium(VI) dialkyl complex [Cr(NC6H3Pri2-2,6)2(CH2CMe3)2] readily eliminates CMe4 in room-temperature hydrocarbon and ether solutions to generate the hexavalent alkylidene species [Cr(NC6H3Pri2-2,6)2)(CMe3)] which can be trapped in the presence of strong donor molecules to give the first stable hexavalent chromium alkylidene complexes [Cr(NC6H3Pri2-2,6)2(CHCMe3(L)](L = thf, PMe3); in aromatic hydrocarbon solutions, the products obtained are those arising from C?H activation across the chromium?carbon double bond.
