Abstract

The objective of this investigation was to demonstrate hindered rotation about single bonds in certain simple paracyolophanes. This purpose waa achieved by thereaolution of a suitable+ substituted paracyclophane which had ten carbon atom in its para-bridge, as exemplified by the compound [10] paracyclophane-l2-carboxylic acid. This acid waa synthesized in three steps from [10) paracyclophane:[101 paracyclophane-+ 12- ...
