Phosgene → Naphthalen-2-yl carbonochloridate

Participants

Reaction Steps

433 g (3.0 mols) of 2-naphthol and 15.7 g of triphenylphosphine are initially introduced into an apparatus as described in Example 1. The mixture is heated to 120° to 125° C. and 325 g of COCl2 are introduced in the course of 12 hours. The reaction mixture is stirred for a further 1 hour, excess phosgene is drawn off in vacuo and crude chloroformic acid 2-naphthyl ester is obtained in a yield of 75% of the theoretical yield.
