A photoredox‐mediated acylation reaction of electron deficient heteroarenes with terminalalkynes is reported. The method relies on oxidative cleavage of phenylacetylenes for generation of acylradicals as a key enabling feature. The reaction is regioselective with broad substrate scope. Quantum yield investigations support a radical chain mechanism.
