Abstract
3-Oxocyclobutanecarboxylic acid was synthesized from methanol,acetone and bromine via bromination,cyclization,salification and hydrolysis in an overall yield of 44.07%.Structure of the product was confirmed by 1H NMR,elementary analysis and MS.This improved method is of many advantages,such as easy operation and low cost,which are feasible to large scale preparation.
