Abstract

5,6,8,9-Tetraaza[3.3]paracyclophane () and the corresponding 14,17-dimethoxy derivative were prepared. and exist as chair and boat conformers, the boat form being energetically favoured. Transannular interaction in and

leads to a hypsochromic shift of the first n → π* absorption.

The [3.3]paracyclophanes
and were prepared; transannular interaction leads to a hypsochromic shift of the first n→π* band.
