✦ Synopsis

College, THREE cases of rearrangement of hydrazobenzenes have been reported in recent years in which the order with respect to acid was between first and second. These-are o-hydrazotoluene* (1.6), 4-methyl-and 4-t-butyl-4'-chlorohydrazobenzene3 (1.58 and 1.51). The last two results were attributed to the part played by the bulky,para subshituents, as proposed earlier in the s-complex theory of the benzidine rearrangement by.Dewar. 4

A new interpretation of variable acid dependence was giv--e,q re,cently by Banthorpe, Hughes and ,Ingold. 5 It is still not know, -however, why some compounds should rearrange by a pro-.oe.ss that is firgt order in acid, and others by one that is

There have been reports of the syntheses of the ortho and para methoxy derivatives of di-t\_butylphenyl carbinollV2 and more recently there has been a report of the preparation of the parent compound 13. We report herein the preparation and characterization of i, its rearrangement to the isomeric se
