Novel Desulphurization of Thiourea Derivatives by Alkaline Autoxidation

Autoxidation of 1,3-disubstituted thioureas in the presence of oxygen and tertiary butoxide in tertiary butanol afforded the corresponding ureas in good yields together with small amounts of the corresponding guanidines while the same treatment of benz- or naphth-imidazole-2-thiones gave the parent imidazoles and the 2-sulphonic acids.

Molecular structure and acid/base properties of 1,2-dihydro-1,3,5-triazine derivatives

It is shown that guanidine and its N,N-dimethyl-derivative react with substituted carbodiimides, affording hitherto unknown 1,2-dihydro-1,2,3-triazine derivatives. The structures of three novel compounds of this type and their perchlorate salts were elucidated by spectroscopic (IR, 1H and 13C NMR and 15N solid-state NMR) and X-ray diffraction methods. The acid/base properties were also determined experimentally and by using DFT calculations with the B3LYP functional. The most basic compound was found to be dihydrotriazine 3, the basicity of which with the pKa value of 23.3 is of the same order of magnitude as that of tetramethylguanidine. Acidity measurements revealed that all the compounds studied are very weak acids with pKa values in the range of 25.8-30.8 pKa units in acetonitrile.

Benzenetellurinic Mixed Anhydrides as Mild Oxidizing Agents

Three benzenetellurinic mixed anhydrides. i. e. benzenetellurinyl acetate, trifluoroacetate, and trifluoromethanesulfonate, have been found to be mild oxidizing agents for various substrates such as thiol, phosphine, acyloin, α-hydroxy ester, catechol, hydroquinone, thiourea, and thioamide.The reactions towards the last two substrates are highly chemoselective, depending on both the reagent and substrate.
