The resulting alpha-diazocarbonyl intermediates undergo a (3 + 2)pcycloaddition at room temperature with conjugated olefins and benzynes. Interestingly, under the current conditions, the resulting cycloaddition products underwent either N-acylation (with excess alpha-diazo-beta-carbonyl phosphonates) or Michael addition (with conjugated olefins).1 aPhatake, Ravindra, S.1 aMullapudi, Venkannababu1 aWakchaure, Vivek, C.1 aRamana, Chepuri, V.  uhttps://library.ncl.res.in/content/fluoride-mediated-dephosphonylation-alpha-diazo-beta-carbonyl-phosphonates
