Abstract

In the case of the recently synthesised tetracyclo[6.4.0.04,12.05,9]dodeca-2,6-diene (13) with its considerable, PE-spectroscopically determined β-parameter, the photochemical, triplet-sensitised [2 + 2]-cycloaddition proceeds with preparatively useful selectivity (45-70%). However, despite the large β-parameter of the related homodiene (21), a [2 + 2]-photocycloaddition is no longer attainable and with the corresponding lower homologue (20) occurs only in very low yield (approx. 6%).
