Abstract
The reaction of F-dimethylketene 3 and diphenylcyclopropenone 7 in benzene solution affords 4-fluorocarbonyl-4-trifluoromethyl-1,2-diphenyltriafulvene 10. A mechanism of the cycloaddition through the intermediates F-methacryloyl fluoride 11 and the oxetane 12 is suggested. A contribution of the dipolar structure 10a is indicated. The cycloaddition of 3 and cyclopropenones constitutes a synthetic route to both symmetrical and unsymmetrical triafulvenes.
