Resumo(s)
Transient azovinylphosphonates, generated in situ by base induced dehydrohalogenation
of the corresponding 2-bromo- and 2-chloro-acetylphosphonate- tertbutoxycarbonyl
hydrazones are intercepted by electron rich alkenes and heterocycles in hetero Diels-Alder reactions, producing tetrahydopyridazine-3-phosphonates or open chain α-hydrazono phosphonates.
