• 論文の詳細を見る

• The dipole moments of some pyrimidine, pyridazine, and their N-oxides (I to VIII) were measured in benzene solution at 25°. In alkoxy derivatives, the moments of two forms, cis and trans were considered by the bending structure of alkoxyl group, and the respective vectorical sums were calculated. Alkoxydiazines whose respective alkoxyl group is attached to the neighboring position of nitrogen atom showed all to exist as cis form. By the steric hindrance of cis form, in the alkoxy-diazine mono N-oxide the oxygen atom was postulated to attach to the nitrogen atom distant from the alkoxyl group.
