Abstract

Introduction As part of work on the Hammett equation we required a number of 4- and 5-substituted 2-tert.buty1benzoic acids. In the present paper we describe the preparation of sixteen of such acids; the dissociation constants are to be discussed later. ... Preparations The substituted 2-tert.butylbenzoic acids were prepared by classic reactions; these are shown in diagram I for the 5-substituted, in diagram I1 for the Csubstituted 2-tert.butylbenzoic acids. In diagram ...
