ABSTRACT:
Compounds containing the butenolide ring have a wide variety of chemical uses. The invention is a method of synthesizing .beta.-halobutenolides which are valuable intermediates in preparing a variety of butenolide ring containing compounds. The method comprises reacting an acetylenic alcohol with a mercuric halide to provide a vinylmercuric halide and carbonylating the vinylmercuric halide to provide a .beta.-halobutenolide.
