工业催化剂Amberlyst-15是一种价廉、易操作、易回收的磺酸树脂，可实现X、S与亚甲基活性化合物的氧化偶联，产率(55~92%)和选择性(83~99%)。该方法完全不含金属，原子经济性很高(99.2%)。
The oxidative coupling of xanthene and thioxanthene with methylene active compounds can be achieved in good yields (55–92%) and selectivities (83–99%) by using the commercial catalyst Amberlyst-15, an inexpensive, safe to handle and easy to recycle sulfonic resin. The method is completely metal-free and shows a very high atom economy (99.2%).
