Herein, we report the photocatalytic decarboxylative alkenylation reactions of N-(acyloxy)phthalimide derived from α-amino and α-hydroxy acids with 1,1-diarylethene, and with cinnamic acid derivatives through double decarboxylation, using sodium iodide and triphenylphosphine as redox catalysts. The reaction proceeds under mild irradiation conditions with visible blue light (440 nm or 456 nm) in an
在本文中,我们报道了使用碘化钠和三苯基膦作为氧化还原催化剂,由α-氨基和α-羟基酸衍生的N-(酰氧基)邻苯二甲酰亚胺与1,1-二芳基乙烯和肉桂酸衍生物通过双重脱羧的光催化脱羧烯基化反应。。该反应在丙酮溶剂中在温和的辐照条件下用可见的蓝光(440 nm或456 nm)进行,而无需使用基于过渡金属或有机染料的光氧化还原催化剂。反应通过N-(酰氧基)邻苯二甲酰亚胺和NaI / PPh 3的瞬时自组装生色团的光活化而进行。溶剂化在反应性中起关键作用。
