An intramolecular hydroacylation of olefins with carboxylic acids (CAs) has been developed, which is based on visible-light photoredox/boronic acid catalysis. The direct use of CAs as acyl-radical precursors was made possible with the aid of boronic acid, and CAs were easily converted into the corresponding cyclic ketones without the need for any stoichiometric activating reagents.
已经开发了一种基于可见光光氧化还原/硼酸催化的烯烃与羧酸 (CA) 的分子内加氢酰化。在硼酸的帮助下,CAs 作为酰基自由基前体的直接使用成为可能,并且 CAs 很容易转化为相应的环酮,而不需要任何化学计量的活化试剂。
