以可简单分离回收、可反复使用为目标,详细介绍了相转移催化的变化发展过 程.通过对溶剂的选择,使得催化剂选择性地溶解在某一液相中,而使产物溶解在 另一液相中,如水-有机两相催化体系;通过温度的变化,简单地实现了在较高温 度下反应为均相体系以提高催化剂的活性,而在较低温度下实现了催化剂与产物不 相溶使得催化剂得以简单分离,如温控型水-有机两相催化体系、氟-有机两相催化 体系、温控型含氟催化剂、温控型有机金属催化剂等.

The development of recyclable process for organometallic catalysts by simple phase separation has been reviewed . Selective dissolution of catalyst in one liquid phase while substrate and product in the other can be attained by choosing suitable solvent. A homogeneous reaction and two-phase separation process were achieved. By tuning the reaction temperature, this method has been successfully applied in temperature-dependent aqueous biphasic and fluorous biphasic systems with fluorous or organometallic catalyst.
