Gold, gold, or …︁ gold? It depends on the (gold) catalyst whether the product of thermodynamic or kinetic control is formed in an unprecedented hydrophosphoryloxylation approach to enolphosphates (see scheme). A third catalyst, [(C6F5)3PAuOTf], was found to be exceedingly effective for the previously unknown isomerization of kineticenolphosphates to the thermodynamicallyfavoredisomers. Tf=tri
黄金,黄金还是…︁黄金?是否以空前的烯醇磷酸盐加氢磷酰氧基化方法形成热力学或动力学控制产物取决于(金)催化剂(参见方案)。发现第三种催化剂[(C 6 F 5)3 PAuOTf]对于动力学烯醇磷酸酯到热力学上有利的异构体的以前未知的异构化非常有效。Tf =三氟甲磺酰基;R =烷基,环己基,Ph。
