Abstract
Visible light has a dramatic effect on the oxidation of benzylic and allylic alcohols, including those deactivated by electron-withdrawing groups, and β-O-4 lignin models, using catalytic amounts of the organo-oxidant 2,3-dichloro-5,6-dicyano-1,4-benzoquinone. Sodium nitrite or tert-butyl nitrite is used as cocatalyst, and oxygen is employed as the terminal oxidant.
摘要
可见光对苄醇和烯丙醇的氧化具有显著影响，包括那些被吸电子基团钝化的醇以及β-O-4木质素模型，使用催化量的有机氧化剂2,3-二氯-5,6-二氰基-1,4-苯醌。亚硝酸钠或亚硝酸叔丁酯用作助催化剂，氧气用作终端氧化剂。
