We developed a new means of activating aldoximes by an in situ generated thiocyanate radical from ammonium thiocyanate and molecular oxygen at room temperature. With a catalytic amount of organic dye aizenuranine as the photocatalyst, the dehydration of aldoximes proceeds smoothly under visible light irradiation, providing a simple to handle, excellent functional group tolerance, and metal-free protocol
我们开发了一种通过在室温下从硫氰酸铵和分子氧中原位生成的硫氰酸根来活化醛肟的新方法。用催化量的有机染料壬酸鸟嘌呤作为光催化剂,醛肟的脱水在可见光照射下平稳进行,提供了简单的操作,优异的官能团耐受性和适用于多种腈的无金属方案。
