Abstract: A concise, efficient method to sulfonyl quinones and sulfonyl-1,4-diols through Ir-catalyzed C–S coupling of quinones with sulfonyl chloride has been developed. Thus, this methodology proves its value as a versatile synthetic tool for a broad ra

The Pd-catalyzed direct C-sulfone formation by C-S coupling of quinones with arylsulfonyl chloride has been developed. This methodology provides an effective, convenient method for the synthesis of arylsulfonyl-quinones and arylsulfonyl-1,4-diols, which a

Hydroxy- (1a-3a) and hydroxyalkyl-substituted benzoquinones (6a-8a, 27a), suited to be immobilized by esterification with polyacrylic acid, are prepared.Their cathodic reduction potential Ep,c (1) correlates linearly with their substituent constant.The cathodic reduction of dioxygen and the palladium(II)-catalyzed anodic oxidation of alkenes are mediated by the benzoquinones 7b, 8b and 27b, respectively. - Key Words: Benzoquinones, substituted / Cyclic voltammetry / Cathodic dioxygen reduction, mediated / Anodic Wacker oxidation, mediated

Benzenesulfinic acid adds to 1,4-quinones in the presence of trifluoroacetic acid affording phenylsulfonylhydroquinones.Addition occurs predominantly at the 6-position for methyl-, tert-butyl- and trifluoromethyl-1,4-benzoquinone, but at the 5-position for methoxy-1,4-benzoquinone.Addition to acyl-1,4-benzoquinones occurs exclusively at the 3-position, but under similar conditions phenylsulfonyl-1,4-benzoquinone affords a mixture of 2,3- and 2,6-bisphenylsulfonylhydroquinones, although the former becomes the sole product in the presence of an excess of trifluoraceticacid.These results are rationalised in terms of selective protonation of the quinone.Oxidation of the phenylsulfonylhydroquinones yields the corresponding quinones which with 1,3-dienes give the expected Diels-Alder adducts.
