A series of new chiral phosphonite ligands were evaluated for the palladium-catalyzed asymmetric Suzuki–Miyaura cross-coupling reactions of aryl chlorides. Ligand 4 gave 91% yield and 78% ee with 0.5 mol % catalyst loading for the coupling of aryl

A functionalized phosphine with a pentaarylbenzene moiety was found to facilitate the palladium-catalyzed Suzuki–Miyaura coupling of aryl chlorides. The new ligand achieved high turnover numbers (up to TON 5000).

Cavitands endowed with dialkylsilyl groups are described, involving the 1H NMR spectra of nearby δ 0 areas. The differences of chemical shifts between in- and outwardly directed alkyls toward the cavity disclosed that introverted alkyls were put und

A straightforward route to functionalized pentaarylbenzene derivatives is described, involving the effective lithiation method of 1-iodo-2,3,4,5,6-pentaarylbenzene. The activated pentaarylbenzene is a potential synton for producing organic materials.
