Our group recently discovered the direct visible light activation of aryl-substituted EBX reagents. 14 The generated excited species could be used for the oxidative alkynylation of several functional groups and alkenes. A key advantage of this approach is the simplicity of the procedure, requiring only the irradiation of a mixture of substrates and EBX reagents without the need for fine-tuned photocatalysts and additives. We wondered therefore if this approach would be also successful in the case of the oxyalkynylation of the C-C bond of aryl cyclopropanes.
