Shedding light on azides: [Ru(TPP)CO] (TPP=tetraphenyl porphyrin dianion), white light and O2 were found to be a suitable catalyst combination to perform the annulation of several biaryl azides (see scheme). The high chemoselectivity of the process allows the synthesis of phenanthridines and dihydrophenanthridines in good yield and purity.
发现叠氮化物上的光:[Ru(TPP)CO](TPP =四苯基卟啉二价阴离子),白光和O 2是执行几种联芳基叠氮化物环化反应的合适催化剂组合(请参见方案)。该方法的高化学选择性允许以高收率和纯度合成菲啶和二氢菲啶。
