Stereochemical Elucidation Of The Tetrahydro [2.2]paracyclophane System

Song, Ban-Huat 08 1900 (has links)
The purpose of this investigation is to study the Birch reduction products of [2.2lparacyclophane and of [2.2]paracyclophane- 2-carboxylic acid. The tetrahydro Birch reduction product of [2.2]paracyclophane is shown to be dl stereoisomer, with the olefins of the upper deck only partially overlapping with the olefins of the lower deck. This stereochemical elucidation is accomplished by means of a complete proton nmr analysis of the tetraepoxide derivative. A proposed mechanism supported by VB (valence bond) and MO (molecular orbital) theories for this Birch reduction process is presented.
