Proton and Heavy Atom Motions during the Stepwise Proton Tautomerism of Various Oxalamidines. A Semiempirical PM3-MNDO Study

摘要

The tautomerism of oxalamidine (OA) and the substituted analogs tetraphenyloxalamidine (TPOA), 2,2’-bis-(4,5-dihydro-1,3-diazole) (OA5), 2,2'-bis-(3)4,5,6-tetrahydro-l,3-diazixine) (OA6) and 2,2'-bis-(4,5,6,7-tetra-...
