An efficient heterogeneous catalytic system for photoinduced arylation of phenols has been developed. The method utilized Cu2(BDC)2(DABCO) (BDC = benzene-1,4-dicarboxylate; DABCO = 1,4-diazabicyclo[2.2.2]octane) as sole photocatalyst. Optimal results were obtained when tBuOLi base, acetylacetone as ligand, and CH3CN solvent were employed in the presence of 365 nm light. Preliminary control experiments to elucidate structure/activity relationship confirmed the contribution of copper metal, BDC linker, and DABCO ligand. Furthermore, the catalyst is heterogeneous and could be recycled for at least 7 times.

迈向金属有机骨架的光学应用:Cu-MOFs作为唯一的非均相光催化剂,可在室温下芳构化苯酚

已开发出一种有效的多相催化体系,用于苯酚的光致芳基化。该方法利用Cu 2(BDC)2(DABCO)(BDC =苯-1,4-二羧酸苯; DABCO = 1,4-二氮杂双环[2.2.2]辛烷)作为唯一的光催化剂。当在365 nm光线下使用t BuOLi碱,乙酰丙酮作为配体和CH 3 CN溶剂时,可获得最佳结果。初步的对照实验阐明了结构/活性关系,证实了铜金属,BDC接头和DABCO配体的贡献。此外,该催化剂是非均相的,可以循环使用至少7次。
