摘要：
A simple and convenient visible-light-mediated method has been developed for the construction of beta-ketosulfones via aerobic oxidative difunctionalization of alkynes with arylazo sulfones and dioxygen in air under photocatalyst-free conditions. The present photochemical methodology provides a facile and attractive protocol to construct a series of beta-ketosulfones in moderate to good yields. (C) 2019 Elsevier Ltd. All rights reserved.
