Abstract

Syntheses of a series of l-alkyl-l-(2-naphthyl) ethenes (where the alkyl group R= Me, Et, n-Pr, i-Pr, and t-Bu) from alkyl 2-naphthyl ketones by Grignard and Wittig methods are described. Comparison of ultraviolet absorption spectra of the alkenes shows a shift, Au, to higher frequency of the major absorption maximum in the order t-Bu>> 2-Pr> n-Pr= Et= Me> H (taken aa standard). From general appearances of the spectra and examination of ...
