Treatment of trans-chalcone with dibenzo-7-phosphanorbornadiene EtOPA (A = C14H10, anthracene), a source of ethoxyphosphinidene, followed by formal elimination of ethanol yields 3,5-diphenyl-2-phosphafuran (DPF) in 43% yield. We show that the phosphadiene moiety of DPF is a potent diene in the Diels?Alder reaction and reacts with dienophiles dimethyl acetylenedicarboxylate (DPF·DMAD, 68%), norbornene (DPF·norbornene, 73%), and ethylene (DPF·C2H4, 80%) under ambient conditions. Mild heating of DPF·C2H4 results in the corresponding retro-Diels?Alder reaction, establishing DPF as a molecule that is able to reversibly bind ethylene.

The reaction between (chlorophosphinidene)pentacarbonyltungsten and benzylideneacetophenone affords a [4 + 1] adduct whose dehydrochlorination by N-methylimidazole affords a 2-phosphafuran complex. Upon further reaction, the phosphafuran is displaced from
