Abstract
2-Methyl-1-phenyl-1,2-dihydro-3,6-pyridazinedione Cia) reacts with tri alkyl phosphites (III) in the absence of solvent to give compounds IVa ,b. I-Phenyl-l,2-dihydro-3,6-pyridazinedione (Ib) reacts with III in t he abscence of solvent whereby alkylation products VIIa,b are formed. Alkylation products IXa,b and Xa-e are similarly formed upon reacting 2,3-dihydro-1,4-phthalazinediones IIa,b with the same phosphite ester under the same experimental conditions.
