for the rapid enhancement of molecularcomplexity. Furthermore, in the structurally similar system created by the formal fusion of the norbornenyl skeleton with an aromatic ring, the ‘nortricyclyl’ radical is delocalised in the originally aromatic π-system. Ring-opening of this ‘nortricyclyl’ radical
