Abstract

Halogenation O 0235Simple and Efficient Methods for Selective Preparation of α-Mono or α,α-Dichloro Ketones and β-Ketoesters by Using DCDMH. -Optimum reaction conditions are studied for the selective preparation of α-mono or α,α-dichloro ketones and β-ketoesters using 1,3-dichloro-5,5-dimethylhydantoin (DCDMH). The structure of some side-products is also reported. -(CHEN, Z.; ZHOU, B.; CAI, H.; ZHU, W.; ZOU*, X.; Green
