Reaktionsschritte
138 g of dimethyl phenylphosphonate are slowly added at 20° C. under nitrogen to a solution of 120.5 g of methyl 2-chloroacrylate and 94 g of phenol. After a reaction time of 3 hours at 70° C. phenetole is removed by vacuum distillation. The residue represents 267 g of crude product with a 93.0% purity, which corresponds to a theoretical yield of 90.1%.
