The oxidative carbonylation of -protected indoles was investigated to directly synthesize indole-3-carboxylic acids. Using Rh(III)-zeolites as heterogeneous catalysts, the single-site Rh-species reach unprecedented activities (>100 turnovers), while the metal is readily recovered after reaction. X-ray absorption spectroscopy (XAS) provided evidence for site-isolation of Rh(III) species on the zeolite.
研究了 - 保护吲哚的氧化羰基化反应，以直接合成吲哚-3-羧酸。使用 Rh(III)-沸石作为多相催化剂，单原子 Rh 物种表现出前所未有的活性（>100 次周转），并且金属在反应后易于回收。X 射线吸收光谱（XAS）为沸石上 Rh(III) 物种的位隔离提供了证据。
