formaldehyde was used as a formylating reagent in a homologation reaction with nonstabilized diazo compounds, enabled by UV photolysis of bench-stable oxadiazolines in a flow photoreactor. Various aliphatic aldehydes were synthesized along with the corresponding derivatized alcohols and benzimidazoles. No transition-metal catalyst or additive was required to affect the reaction, which proceeded at room temperature
廉价和易于获得的
甲醛水溶液在与不稳定的重氮化合物的同系化反应中用作甲酰化试剂,这是通过在流动光反应器中对台式稳定的恶二唑啉进行紫外线光解而实现的。合成了各种脂族醛以及相应的衍生醇和
苯并咪唑。不需要过渡
金属催化剂或添加剂来影响反应,该反应在室温下进行80分钟。
