我们以前的工作曾报道过一类辅酶B_(12)的模型化合物RCo(Salenn)L(即烷基钴双水场醛乙二胺,L为H_2O或无水)的甲醇溶液在加热或光照条件下产生钴-碳键断裂的反应:Co(Salen)L的生成已为电子光谱证实,但烷基自由基寿命短(例如CH_3·的寿命只有10~(-3)s),用一般方法很难检测。 我们采用了检测短寿命自由基的新方法——自旋捕集技术,对RCo(Salen)L溶液光
Our previous work reported that a methanolic solution of a model compound RCo (Salenn) L of Coenzyme B_ (12) (ie Alkalicldicarbonate H 2 O 2, L is H_2O or anhydrous) under heating or light conditions Under the cobalt-carbon bond cleavage reaction: The formation of Co (Salen) L has been confirmed by electron spectroscopy, but the short life of alkyl radicals (for example, the life expectancy of CH_3 is only 10 ~ (-3) s) Hard to detect. We have adopted a new method for detecting short-lived free radicals - spin-trapping technology for the RCo (Salen) L solution light
