The ratios 1∶1 and 1∶2 of the methoxyl adducts of the 1,4-diazinium ions in the sodium methoxide-methanol-D4 system and the equilibrium constants for the transformations of the mono-adducts into the diaddition products were determined by PMR spectroscopy \\\\expert2\\nbo\\Chemistry of Heterocyclic Compounds\\1986, v.22, N 10, p. 1118.pdf |
