  • Photoinduced Alcoholysis of α,α,α-Tribromoacetophenone to Benzoylformate
    作者:Yasuji Izawa、Katsuhiro Ishiguro、Hideo Tomioka
    DOI:10.1246/bcsj.56.1490
    日期:1983.5
    Irradiation of p-substituted α,α,α-tribromoacetophenones (1) in O2-saturated alcohols (MeOH, prim. and sec. alcohols) afforded a new alcoholysis product, benzoylformate (2), in good yield (75–85%) along with benzoate and radical (reduction) products. Sensitization experiments showed that 2 was derived from the triplet excited 1. Formation of 2 as well as the decomposition rate of 1 were greatly accelerated
    对 O2 饱和醇(MeOH、主醇和仲醇)中的 p-取代 α,α,α-三溴苯乙酮 (1) 进行辐照,得到一种新的醇解产物苯甲酰甲酸酯 (2),收率良好 (75–85%)以及苯甲酸盐和自由基(还原)产物。敏化实验表明,2 源自激发的三重态 1。氧极大地加速了 2 的形成以及 1 的分解速率,这可能是由于 1 的正常禁止的 S0→T1 转变的参与所致氧-1 电荷转移复合物。1 导致 2 的光醇解中可能的中间体的独立合成和反应表明 2 是由初始光醇解产物 α,α-二溴-α-烷氧基苯乙酮的自发(暗)反应形成的。

    with bases have been systematically examined. Monomeric C-methoxy-imines are available from some of these reactions. C-methoxyphenacylarylamines, made by two routes, were converted into monomeric imines on treatment with noble-metal catalysts. The boron trifluoridecatalysed reactions of aryl aldehydes with sulphonamides provide a new and convenient route to N-sulphonylarylimines.
