Visible‐Light‐Induced Arenethiolate as a Dual Function Catalyst Synthesis of Fluorine‐Containing Siloxane through Hydrofluoroalkylation of Alkenyl Siloxane

Fluorine‐containing siloxanes are useful synthetic intermediates in a variety of organic transformations and material chemistry due to their high reactivity. Fluorine‐containing siloxanes can also be used as coupling agents and wetting agents. However, the catalytic synthesis of fluorine‐containing siloxanes remains elusive. Here, we reported a simple and mild method for hydrofluoroalkylation of alkenylsiloxanes with trifluoromethyl arenes under visible‐light‐induced arenethiolate as a dual functional catalyst, affording a range of valuable 1,2‐disubstituted fluorine‐containing siloxanes in up to 57% yield. This research was distinguished by broad functional group tolerance, moderate to good yields and gram‐scale synthesis.
