摘要

在无氧和无溶剂条件下，开发了一种环境友好的磷钨酸催化交叉脱氢偶联反应，用于合成 9-取代-9H-呫吨。该反应经济实用，对底物具有良好的耐受性，通过调节呫吨和酮的比例，合成了多种 9-取代-9H-呫吨，收率从中等到极佳（22 例，收率高达 99%）。通过测试光电化学性质，一些氧杂蒽衍生物（10c、12c、13c 和 2d）显示出稳定的光电流值，尤其是 2d 具有更好的阴极光电流值和应用潜力。

An environment-friendly phosphotungstic acid catalyzed cross-dehydrogenative coupling reaction to synthesize 9-substituted-9H-xanthenes with photoelectrochemical performance

An environment-friendly phosphotungstic acid catalyzed cross-dehydrogenative coupling reaction for the synthesis of 9-substituted-9H-xanthenes under oxygen and solvent-free conditions have been developed. The economic and practical reaction exhibited good substrate applicability tolerance, various 9-substituted-9H-xanthenes were synthesized in moderate to excellent yields by tuning the ratio of xanthenes and ketones (22 examples, up to 99% yield). By testing the photoelectrochemical performance, some of the xanthene derivatives (10c, 12c, 13c and 2d) showed stable photocurrent value, especially 2d had better cathode photocurrent value and application potential.
