Highly oxidizing nitrate radicals (NO3˙) are easily accessed from readily available nitrate salts by visible light photoredox catalysis using a purely organic dye as the catalyst and oxygen as the terminal oxidant. The interaction of the excited catalyst and nitrate anions was studied by spectroscopic methods to elucidate the mechanism, and the method was applied to the NO3˙ induced oxidation of alkynes and alcohols.
通过使用纯有机染料作为催化剂和氧气作为终端氧化剂的可见光光氧化还原催化作用，很容易从易得的硝酸盐中获取高氧化性的硝酸根自由基（NO3˙）。通过光谱方法研究了激发态催化剂与硝酸根阴离子的相互作用以阐明其机理，并将该方法应用于NO3˙引发的炔烃和醇类的氧化反应。
