Abstract

Abstract New examples of the ortho effect in bisphenol A derivatives including interaction of the hydrogen of the ortho-hydroxy group with the neighbouring aromatic ring have been observed. The characteristic ions [M [BOND] PhOH]+ middot;(m/z= 134) and [M [BOND] CH 3 [BOND] PhOH]+(m/z= 119) were shown to form through the hydrogen transfer from hydroxy and isopropyl groups, respectively. The spectra of cyclic derivatives having ortho- ...
