An efficient, catalyst/photocatalyst-free, and cost-effective methodology for the decarboxylative alkylation of α,β-unsaturated carboxylic acids to synthesize β,γ-unsaturated nitriles has been developed. The reaction proceeded in an environmentally benign atmosphere of blue light-emitting diode irradiation with K2CO3 and water at room temperature. The methodology worked for a wide range of substrates
已开发出一种高效、无催化剂/光催化剂且具有成本效益的方法,用于α , β -不饱和羧酸的脱羧烷基化以合成β , γ -不饱和腈。该反应在室温下用 K 2 CO 3和水在蓝光发光二极管照射的环境友好气氛中进行。该方法适用于多种基材(22 个示例),产率高达 83%。该协议也适用于克级合成。
