  新型长寿命双杀菌双（dipyrrinato）锌（II）配合物的聚合物封装，可用作光动力疗法光敏剂。

  摘要：

  在过去的几年中，使用光动力疗法（PDT）来治疗癌症已受到越来越多的关注。但是，临床上使用的光敏剂（PSs）具有一些局限性，包括水溶性差，肝毒性，光漂白，聚集和从体内清除缓慢，因此，新型PSs的设计引起了人们的极大兴趣。我们提出使用双（dipyrrinato）锌（II）配合物作为有效的PDT PS具有超长的使用寿命。基于重原子效应，这些配合物的系统间交叉将激发态从单重态变为三重态，从而实现了单重态氧的产生。为了克服在水中淬灭作用的局限性并提高水溶性，将铅化合物3包封在聚合物基质中。

  日期：2021.1.15

  A generalized protocol for the reductive carbonylation of (hetero) aryl halides and triflates under CO gas‐free conditions using Pd/Co2(CO)8 and triethylsilane has been developed. The mild reaction conditions, enhanced safety, and wide substrate scope highlight its importance in routine organic synthesis.

• Dynamic Kinetic Resolution of Alcohols by Enantioselective Silylation Enabled by Two Orthogonal Transition‐Metal Catalysts
  作者：Jan Seliger、Martin Oestreich

  DOI：10.1002/anie.202010484

  日期：2021.1.4

  A nonenzymatic dynamic kinetic resolution of acyclic and cyclic benzylic alcohols is reported. The approach merges rapid transition‐metal‐catalyzed alcohol racemization and enantioselective Cu‐H‐catalyzed dehydrogenative Si‐O coupling of alcohols and hydrosilanes. The catalytic processes are orthogonal, and the racemization catalyst does not promote any background reactions such as the racemization
