From diphosphino-functionalized 1,3-dialkylimidazolium cations to imidazolones through dehydrogenative C-N coupling

Diphosphino-functionalized 1,3-dialkylimidazolium salts react with KOH affording amine/formamide open-chain products, which fully revert to the imidazolium cation by treatment with a variety of acids or are converted to 2-imidazolones by noncatalyzed intramolecular dehydrogenative C-N coupling, a process that is modulated by coordination of the phosphino functionalities to transition metals. Breaking and reforming the imidazolium ring! Diphosphino-functionalized 1,3-dialkylimidazolium salts react with KOH affording amine/formamide open-chain products, which fully revert to the imidazolium cation by treatment with a variety of acids or are converted to 2-imidazolones by noncatalyzed intramolecular dehydrogenative C-N coupling (see scheme, Tf = triflate).

Synthesis of 2-imidazolones and 2-iminoimidazoles

Convenient methods for the direct conversion of imidazolium salts to the corresponding 2-imidazolone or 2-imino imidazole derivatives have been developed. Treatment of the salt with commercial bleach leads to effective oxidation at C2 and the formation of the corresponding imidazolone. Alternatively, treatment of the salt with an N-chloro amide affords the corresponding protected 2-amino derivative in good yield.

Dye sensitized photooxygenation of imidazolin-2-ones

Imidazolin-2-ones(13-18) on photooxygenation in the presence of methylene blue yielded the corresponding diacylureas as the only products isolated at room temperature. The rate of photooxygenation followed the order 16>17>18>13>14>15. The reaction was als
