Abstract

Tetra-arylcyclobutenyl cations are formed in quantitative yield in the reaction of diarylacetylenes with strong proton acids. NMR and UV measurements give evidence of a stereospecific cycloaddition reaction of the diarylacetylenes. SCF calculations according to Pariser, Parr and Pople show, that homo-conjugation must exist in the tetra-arylcyclobutenyl cations.
