A Mo(VI)-catalyzed deoxygenation of epoxides to alkenes has been achieved using a sacrificial alcohol as a reductant. The MoO₂(dtc)₂ (dtc = diethyl dithiocarbamate) was proved to be a better catalyst than the other molybdenum based catalysts examined. Of the reducing agents examined, secondary alcohol, 2,4-dimethyl-3-pentanol was the most efficient and proved to be a better potential hydrogen donor. The reaction is very clean and the product yield ranges from moderate to excellent, with almost no byproduct(s) detected except, 2,4-dimethyl-3-pentanone, which is the oxidized product of 2,4-dimethyl-3-pentanol.

钼催化的环氧化物脱氧成烯烃

使用牺牲醇作为还原剂已经实现了Mo（VI）催化的环氧化物还原为烯烃。事实证明，MoO ₂（dtc）₂（dtc =二乙基二硫代氨基甲酸酯）是一种比其他所研究的钼基催化剂更好的催化剂。在所研究的还原剂中，仲醇2，4-二甲基-3-戊醇是最有效的，并被证明是潜在的更好的氢供体。反应非常干净，产物收率从中等到优异，几乎没有副产物被检测到，除了2,4-二甲基-3-戊酮是2,4-二甲基-3-戊醇的氧化产物。 。
