Abstract
Alkynylsilanes are significant structural units frequently used in synthetic chemistry, medicinal chemistry, functional materials, and life sciences. Herein, we report a method for using a hydrogen atom transfer (HAT) strategy in combination with visible-light-driven photocatalysis to achieve a direct coupling reaction between benzene sulfonyl acetylene and tertiary silanes, and a diverse alkynylation of hydrosilanes in the presence of reactive groups was achieved with this strategy. It is important to note that dihydroalkyl/aryl silanes are also suitable for the protocol of HAT photocatalytic of 4CzIPN and quinuclidine.
