ABSTRACT:
An improved method for the synthesis of omega-unsaturated carboxylic acids is disclosed which precludes double bond migration or hydrogenation in order to prepare a high purity product necessary for high resolution in forming a resist by electron beam microlithography. This result can be obtained by a coupling reaction between a Grignard reagent of an unsaturated organochloride compound as defined in the application with a halo magnesium salt of a long chain organic acid.
