posted on 2018-08-06, 15:45 authored by Pritpal SinghThe work described in this thesis is concerned with
the major factors controlling the acid-catalysed rearrangements
of methyl-substituted 1-methoxybenzobarrelenes.
A short summary is presented in chapter one on the
cycloaddition reactions of arynes with arenes, discussing the
principle reactions and factors influencing the orientation of
the 1,4-cycloaddition. Some of the recent advances in the
chemistry of carbocations involved in the secondary rearrangements
of highly substituted benzobarrelenes have been discussed.
Chapter two discusses the reactions of tetrahalogenobenzyne
with mono- and polysubstituted anisoles (e.g. 2-methyl,
2,3-dimethyl and 2,3,5,6-tetramethyl etc.) which results in
the formation of substituted tetrahalogenobenzobarrelenones
and 1-methoxytetrahalogenobenzobarrelenes. A method for the
preparation of 2,3-dimethoxytoluene in high yield has been
presented. [Continues.]
