• We report the visible-light-induced in situ preparation of COCl 2 through the oxygenation of chloroform in the presence of chlorine dioxide, which leads to the safe constructions of carbamoyl chlorides with good-to-high yields and wide substrate scopes. In addition, this method can also be applied to the synthesis of various carbonates. Visible-light-induced oxygenation of chloroform (CHCl 3 ) using chlorine dioxide (ClO 2 &z.rad;) enables the in situ generation of phosgene (COCl 2 ) and the synthesis of carbamoyl chlorides.
