Abstract
1) Alcohols: As high boiling alcohols, β-phenylethyl, benzyl, and α-phenylethyl alcohol, and benzhydrol were reacted with formamide, and it was found that three forms of reaction occured to give respective product of a formate, formylamine, and ether. In other words, the difference in chemical structure appeared in the reaction so that formylamine and ether were chiefly formed from benzhydrol while the formate formation was more likely to occur from β-phenylethyl alcohol.2) Ketoximes: Reaction of acetophenoxime, benzophenoxime, acetoxime, and cyclohexanone oxime with formamide resulted in the reductive activity of formamide to give one product of corresponding formylamines.3) Aromatic Nitroso Compounds: Reaction of nitrosobenzene, 4-nitrosophenetole, and 4-nitrosodimethylaniline with formamide chiefly yielded the corresponding azoxybenzene compounds as the product. However, the nitroso compounds that can easily take the quinoid form were found to prevent the formation of azoxybenzene compound as 4-nitrosophenol, 1-nitroso-2-naphthol, and 1-nitroso-4-naphthol only formed black, amorphous substance of unknown structure.
