A series of alkyl mesylates, dimesylates and alkyl or aryl triflates have been reduced to the corresponding hydrocarbons with nickel(II) chloride dihydrate, an excess of lithium powder and a catalytic amount of DTBB (10 mol%) in THF at room temperature. This methodology applied to enol triflates allowed the preparation of olefins or alkanes depending on the amount of the Ni(II) salt used. The reduction
在室温下,将一系列烷基甲磺酸酯,二甲基酯和烷基或芳基三氟甲磺酸酯与氯化镍(II)二水合物,过量的锂粉和催化量的DTBB(10 mol%)在THF中还原为相应的烃。应用于烯醇三氟甲磺酸酯的该方法学允许根据所使用的Ni(II)盐的量来制备烯烃或烷烃。在上述条件下还原不同的芳族或杂芳族化合物会导致原料的部分或全部还原,该方法是众所周知的桦木反应的合理替代方案。含氘化镍(II)盐的使用可简化氘代产品的制备。
