Abstract

Abstract n-(N, N-Dimethylamino) phenylethynes were satisfactorily prepared by a Wittig reaction between chloromethylene (triphenyl) phosphine ylide and the appropriate n-(N, N- dimethylamino) benzaldehyde, followed by dehydrochlorination with a strong base. The conjugate dimers 1, 4-bis [n-(N, N-dimethylamino) phenyl] buta-1, 3-diyne were obtained by oxidative dimerization with copper (I) chloride. X-ray molecular structure analysis of the ...
