Both of the possible isomeric structures (symmetrical and unsymmetrical) for diphenyl dithiolphthalate and for di-(ptiitrophenyl) dithiolphthalate have been obtained in pure form and structures assigned on the basis of infrared spectra. sym-Diphenyl dithiolphthalate was prepared in 94y0 yield by interaction of sym-phthaloyl chloride, thiophenol and sodium methoxide in methanol solution. By treatment of a mixture of phthalic anhydride and ...
