Introduction

Winston Costain is a notable inventor based in Manchester, GB. He has made significant contributions to the field of chemistry, particularly in the development of lactones. His innovative work has led to the creation of a patent that showcases his expertise and creativity.

Latest Patents

Winston Costain holds a patent for the preparation of lactones, specifically 4-.beta., .beta.-dichlorovinyl (or dibromovinyl)-3,3-dimethylbutyrolactones. This process involves reacting 1,1-dichloro (or dibromo)-4-methylpenta-1,3-diene with an acid of the formula CH.sub.2 R.CO.sub.2 H in the presence of a metal salt, particularly manganese (III), cerium (IV), or vanadium (V). The method enhances yields when using the anhydride of the acid and the sodium or potassium salt of the acid. Furthermore, treatment of the lactones with an inorganic acid halide results in the formation of a corresponding 4-haloacid halide, which can be transformed into a 4-haloacid ester, ultimately leading to the synthesis of intermediates for insecticides.
