  Flash Photolytic Generation and Study of Ynolate Ions and the Corresponding Ketenes in Aqueous Solution

  摘要：

  Flash photolysis of a series of arylhydroxycyclopropenones (aryl = phenyl, mesityl, 4-methoxyphenyl, 2,4,6-trimethoxyphenyl, and 1-naphthyl) in aqueous solution was found to give arylacetic acids as final products through two successively formed, short-lived reaction intermediates. Rate profiles, the form of acid-base catalysis, and solvent isotope effects identified the first of these intermediates as arylynolate ions, ArC=CO-, and the second as arylketenes, ArCH=C=O; the identity of the ketenes was also confirmed by independent generation through photo-Wolff reaction of corresponding aryl diazo compounds. The kinetic behavior of the arylynolate ions shows that the corresponding arylynols, ArC=COH, are remarkably strong acids, with pK(a) < 3.

  carbonyl-activated methylene and methyl compounds exhibiting no bromo or diazo substituents could be also transformed into dithioesters by the CAT reaction. The structure of three dithioesters was corroborated by X-ray structural analyses. Supplemental materials are available for this article.

  Abstract [3+2]-Cycloaddition of arenediazonium salts with diazo compounds (earlier exemplified only for trimethylsilyldiazomethane and 2,2,2-trifluorodiazoethane) has been developed to include a wide range of readily available α-diazocarbonyl compounds. The resulting 2-aryl-5-acyl-2H-tetrazoles are of high value in medicinal chemistry. [3+2]-Cycloaddition of arenediazonium salts with diazo compounds

  A highly efficient synthesis of α-diazoketone was achieved by simply stirring the mixture of 1,3-diketone, TsN3, and MeNH2 in EtOH. It was a tandem reaction including a novel primary amine-catalyzed Regitz diazo transfer of 1,3-diketone and a novel primary amine-mediated C–C bond cleavage of 2-diazo-1,3-diketone.

  A highly straightforward route to enantiomerically highly enriched cis-2,3-dihydrobenzofurans has been achieved via addition of α-diazocarbonyl compounds to in situ generated o-QMs catalyzed by a chiral Brønsted acid. This catalytic strategy provides a direct access to 2,3-dihydrobenzofurans in high yields and with up to 91:9 dr and 99:1 er at ambient temperature. Moreover, a unique phenonium-type

  Ten new α-diazo-β-oxoaldehydes were condensed with aniline, ammonia, hydroxylamine, and semicarbazide to yield new 4-acyl-(1-substituted)-1H-1,2,3-triazoles in moderate-to-good yields. The method is simple and regiospecific. The latter feature makes this method superior to the widely used acylacetylene + azide approach.
