  含杂芳基的伯醇和仲醇中的无金属好氧氧化选择性C–C键裂解。

  摘要：

  据报道，伯和仲杂芳基醇中无过渡金属的需氧氧化选择性C–C键断裂反应。该反应是高效的并且耐受各种杂芳基醇，产生羧酸衍生物和中性杂芳族化合物。实验研究与密度泛函理论计算相结合，揭示了选择性C–C键断裂的机理。该策略还提供了另一种简单的羧化反应方法。

  Site-selective mono-oxidative addition of active zinc into carbon–bromine bond of dibrominated-thiophenes: preparation of thienylzinc reagents and their applications

  摘要：

  A facile protocol for the preparation of 3-bromo-2-thienylzinc bromide A and 5-bromo-2-thienylzinc bromide B has been developed. It has been successfully accomplished by a site-selective oxidative addition of active zinc into a chemically pseudo-equivalent or equivalent carbon-bromine bond, respectively. The subsequent cross-coupling reactions of the organozincs were also successfully carried out under mild conditions providing the corresponding products in moderate to high yields.

  aerobic oxidative selective C–C bond-cleavage reaction in primary and secondary heteroaryl alcohols is reported. This reaction was highly efficient and tolerated various heteroaryl alcohols, generating a carboxylic acid derivative and a neutral heteroaromatic compound. Experimental studies combined with density functional theory calculations revealed the mechanism underlying the selective C–C bond
