  We report a method for addition of α-bromophenylacetic acids to vinyl CC bonds in styrenes to afford γ-lactones. Reactions employed a simple cobalt catalyst Co(NO3)2·6H2O in the presence of dipivaloylmethane (dpm) ligand. Many functionalities including halogen, ester, and nitro groups were compatible with reaction conditions. If α-bromoesters were used, vinylacetates were the major products.

  我们报告了一种将 α-溴苯乙酸添加到苯乙烯中的乙烯基 C C 键以提供 γ-内酯的方法。在二戊酰甲烷 (dpm) 配体存在下，反应使用简单的钴催化剂 Co(NO 3 ) 2 ·6H 2 O。许多官能团，包括卤素、酯和硝基，都与反应条件相容。如果使用 α-溴代酯，醋酸乙烯酯是主要产品。

  Direct gamma-lactone formation via visible-light photoredox catalysis has been achieved efficiently including hydroxylalkylation of aromatic alkenes and transesterification. The present photocatalytic protocol has good regioselectivity and substrate compatibility, affording a novel way to intermolecular gamma-lactone synthesis by the reaction of styrenes with alpha-bromo esters in the absence of any external oxidants.
