A convenient synthesis of 4-substituted-4′-(2-thienyl)-2,2′-bithiazoles as potential phototoxic agents
Singh,Naithani,Aggarwal,Prakash
, p. 3747 - 3751 (2001)
Alpha-tosyloxyacetylthiophene (3), obtained by the hypervalent iodine oxidation of 2-acetylthiophene (2) using [hydroxy(tosyloxy)iodo]benzene (HTIB), on treatment with rubeanic acid exclusively generates 4-(2-thienyl)thiazole-2-thiocarboxamide (4) which upon subsequent treatment with a variety of alpha-tosyloxyketones (5) affords the title compounds (6) in excellent yields.
Novel α-tosyloxylation of ketones catalyzed by the in situ generated hypoiodous acid from alkyl iodide
Zhang, Bijun,Han, Liuquan,Hu, Jiantao,Yan, Jie
, p. 5851 - 5854 (2015/01/16)
Using a catalytic amount of 1-iodopropane, a novel and efficient procedure has been developed for direct preparation of α-tosyloxyketones from ketones. In this protocol, 1-iodopropane is first oxidized into iodosylpropane, which decomposes to form the key

supporting information, p. 3264 - 3270 (2015/10/06)
With 1,1,1-trifluoro-2-iodoethane as catalyst, a novel and efficient procedure has been developed for preparation of α-tosyloxyketones from ketones. In this protocol, 1,1,1-trifluoro-2-iodoethane is first oxidized by m-chloroperbenzoic acid to a hypervale
Iodine-mediated α-sulfonyloxylation of alkyl aryl ketones with oxone and sulfonic acids
Kikui, Hiroki,Moriyama, Katsuhiko,Togo, Hideo
, p. 791 - 797 (2013/04/10)
Alkyl aryl ketones are converted into the corresponding α-sulfonyloxyketones, in moderate to excellent yields, via a novel procedure that utilizes Oxone, p-toluenesulfonic acid or methanesulfonic acid and molecular iodine in a mixture of aceton
An iodobenzene-catalysed domino route toward quinoxaline derivatives from simple ketones and o-phenylenediamines in one pot
Li, Xiaoqing,Zhou, Can,Hu, Zhiyan,Xu, Xiangsheng
, p. 579 - 581 (2013/10/22)
An iodobenzene-catalysed domino route to quinoxalines from ketones and o-phenylenediamines in one pot has been developed. This transformation consisted of the generation of Koser's generation, α-tosyloxylation of ketones, nucleophilic substitution and intramolecular dehydration with o-phenylenediamines, and dehydrogenation.
