6-tetramethyl-cyclohex-1-yl toluene-p-sulphonate to (PPh3)2CoBr2,(PPh3)2NiBr2, and hydroxo-cobalamin, all reduced with sodium borohydride, or to (Me)2CuLi, provide firm evidence for a novel mechanism of the 1,2-bond shift rearrangements catalysed by vitamin B12 coenzyme.
在环境温度为2,2,6,6-四甲基-环己-1-基甲苯-对磺酸盐氧化成(PPh 3)2 CoBr 2,(PPh 3)2 NiBr 2和均被硼氢化钠还原或还原为(Me)2 CuLi的羟钴胺素,为维生素B 12辅酶催化的1,2-键移位重排的新机理提供了有力的证据。
