cyanine dyes and that the reductive quenching of radical intermediates is at least partially due to hydrogen abstraction from the solvent. As a consequence, a reductive cyclization of the starting materials is favored in CD2Cl2 solutions as shown for two β‐(3‐iodopropoxy)‐substituted tetronates, which underwent in dichloromethane almost exclusive reduction, but gave predominantly the cyclization products
