Abstract:
Ben zylic and pseudo-benzylic positions provide a convenient site in nucleophilic substitution reactions, which is attributed to involvement of some stable carbocationic-type reaction intermediates, it is observed that thiourea and potassium phthalimide can readily attach both a and a' positions in a,a>-dibromc-oi1ho-xylene to produce a,a'*bis (isothiouranium)-ortho-xylene and a,a'-bis(phthalimide)-ortho-xylene respectively as supported by their IR, 1H nmr, 13C nmr, Mass spectra and micro analysis.
Keywords:pseudo-benzylic; Nucleophilic; phthalimide; 1H nmr
