Ni‐catalyzed decarboxylative cross‐coupling of potassium polyfluorobenzoates with unactivated phenol and phenylmethanol derivatives is described. This novel transformation provides a practical and efficient protocol towards the synthesis of important polyfluorobiaryls and polyfluorinated diarylmethanes, and greatly enlarges the range of electrophiles utilized in decarboxylative coupling. Remarkably, preliminary

A novel water-soluble photochemical microreactor has been prepared. A perbutylated cyclodextrin bearing seven naphthalenesulfonate antenna chromophores (Bu-CD-N7) displays improved solubilization of hydrophobic guests in comparison with the unbutylated material (CD-N7). The photophysical properties of Bu-CD-N7 are similar to those of the CD-N7. The naphthyl chromophores of Bu-CD-N7 were used to sensitize
