Carbon-13 NMR and mass spectra of some N-arylmaleimides substituted at the 2-position

Abstract

Carbon-13 NMR of several novel Af-arylmalelmldes substituted at 2-posltlons are presented. In addition, mass spectra of four of the imldes substituted with chloro or cyclopropylamlno groups are also reported. The data reveal the absence of trace isolmldes in the prepared samples.
