The reactive 1:1 intermediate obtained from the addition of triphenylphosphine to dibenzoylacetylene was trapped by heterocyclic NH-acids such as imidazole, 4-nitroimidazole, or 5-methyl-4-nitroimidazole to produce 2,3,5-trisubstituted furan derivatives.

Protonation of the highly reactive 1:1 intermediates produced in the reaction between alkyl isocyanides and dibenzoylacetylene by saccharin, phthalimide, or 4-methyl-5-nitroimidazole, leads to vinylnitrilium cations, which undergo carbon-centered Michael type addition with the conjugate base of the
