Abstract
The interaction of 2-(phenylthiocarbamoyl) imidazolium inner salts with dimethyl acetylenedicarboxylate produced dimethyl 2-(imidazolin-2-ylidene)-3-thioxobutanedioates in moderate to good yields. The process involved a tandem reaction comprising a 1,3-dipolar cycloaddition and an unprecedented cheletropic elimination of the phenyl isonitrile from a 2-phenyliminodihydrothiophene moiety. NMR and X-ray diffraction studies confirmed that the 2-(imidazolin-2-ylidene)-3-thioxobutanedioates are novel push-pull olefins and have potential applications in nonlinear optical materials.
