thiols and PhSeH (proton source), could regenerate either 1aZn/5Zn and 2Zn respectively, along with the production of nitric oxide (NO) where the yield of NO increases in the order tBuSH ≪ PhCH2SH < PhSH < PhSeH. In contrast to this, 1aFe, 2Fe and 5Fe could affect the direct reduction of NO2− in the absence of protons to generate NO and [(Py2ald)(ONO)Fe}2-μ2-O] (8Fe). Moreover, 8Fe could regenerate 5Fe
一系列新型 Zn( II ) 和 Fe( II ) 化合物 [(Py2ald)M(ER)] (E = S, R = Ph: M = Zn, 1a Zn ; M = Fe, 1a Fe ; E = S,R = 2,6-Me 2 -C 6 H 3 :M = Zn, 1b Zn ;M = Fe, 1b Fe ;E = Se,R = Ph:M = Zn, 2 Zn ; , 2 Fe ) 和 [(Py2ald)M] 2 2+ (M = Zn, 5 Zn ; M = Fe, 5 Fe ) 被提出。 化合物1a Zn可以与亚硝酸盐 (NO 2 − ) 反应生成 [(Py2ald)Zn(ONO)] ( 3 Zn ),经硫醇和 PhSeH(质子源)处理后,可以再生1a Zn / 5 Zn和2 Zn分别随着一氧化氮 (NO) 的产生而增加,其中 NO 的产量按t BuSH ≪ PhCH 2 SH < PhSH
