A one-pot protocol for the fluorosulfation and Suzuki coupling of phenols is described. The tandem reaction proceeds efficiently at room temperature, and various biaryls and biaryl fluorosulfates were obtained in good to excellent yields. Furthermore, biaryl fluorosulfates were utilized as versatile building blocks for the preparation of terphenyls. The Royal Society of Chemistry 2020.

The iron(III) chloride-catalyzed Friedel–Crafts arylation of 4-aryl-4-methoxy-2,5-cyclohexadienones, which were easily prepared by the phenyliodine(III) diacetate (PIDA)-mediated oxidation of 4-arylphenols in methanol, proceeded site-selectively to form meta-terphenyl (2,4-diarylphenol) derivatives in good yields. The subsequent PIDA-mediated oxidation and iron(III) chloride-catalyzed Friedel–Crafts arylation of the resulting products gave the corresponding 2,4,6-triarylphenol derivatives. The present method provides useful highly substituted polyarylated compounds. (Figure presented.).

Palladium nanoparticles stabilised by tris(3-sulfophenyl)phosphine trisodium salt in neat glycerol have been synthesised and fully characterised, starting from both Pd(II) and Pd(0) species. The versatility of this innovative catalytic colloidal solution has been proved by its efficient application in C-X bond formation processes (X=C, N, P, S) and C-C multiple bond hydrogenation reactions. The catalytic glycerol phase could be recycled more than ten times, preserving its activity and selectivity. The scope of each of these processes has demonstrated the power of the as-prepared catalyst, isolating the corresponding expected products in yields higher than 90%. The dual catalytic behaviour of this glycerol phase, associated to the metallic nanocatalysts used in wet medium (molecular- and surface-like behaviour), has allowed attractive applications in one-pot multi-step transformations catalysed by palladium, such as C-C coupling followed by hydrogenation, without isolation of intermediates using only one catalytic precursor.
