Vinogradov, M. G. published the artcileSelective method of 5-chloro-2-pentanone preparation, Synthetic Route of 20117-47-9, the publication is Izvestiya Akademii Nauk, Seriya Khimicheskaya (1995), 774-6, database is CAplus.
5-Chloro-2-pentanone (1) was prepared by reaction of 1-methylcyclobutanol (3) with Ca(OCl)2, followed by decomposition of the 1-methylcyclobutyl hypochlorite in the presence of a FeII salt. The selectivity of 1 formation from 3 was 98%, and the conversion of 3 was 35-40%.
