The behavior of tertiary phosphite esters towards 1,2-dihydro-3,6-pyridazinediones and 2,3-dihydro-1,4-phthalazinediones

2-Methyl-1-phenyl-1,2-dihydro-3,6-pyridazinedione Cia) reacts with trialkyl 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 the abscence of solvent whereby alkylation products VIIa,b are formed. Alkylation products...

Summary:2-Methyl-1-phenyl-1,2-dihydro-3,6-pyridazinedione Cia) reacts with trialkyl 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 the 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.
