left to chance: A convenient protocol for selective cross‐coupling of diazocompounds for the convergent synthesis of alkenes was developed (see scheme; EDG=aryl, heteroaryl, vinyl; R=O‐alkyl, aryl). The selectivity control elements were identified by ReactIR and DFT calculations and provide a framework for the design of viable diazo coupling reactions.
没事了:开发了用于重氮合成烯烃的重氮化合物选择性交叉偶联的便捷方案(见方案; EDG =芳基,杂芳基,乙烯基; R = O-烷基,芳基)。通过ReactIR和DFT计算确定了选择性控制元素,并为可行的重氮偶合反应设计提供了框架。

distinct diazo compounds was described. The reaction produces E-configured trisubstituted alkenes in good yields in the absence of catalysts and additives. The reactive free carbeneintermediates were generated via selective photolysis of one of the two diazo compounds upon blue light irradiation.
