A series of dibenzofurans were efficiently and conveniently synthesized via one-pot consecutive C(sp2)-O bond formation reaction (SNAr) in the presence of anhydrous K2CO3, followed by C(sp 2)-C(sp2) b

An efficient one-pot synthesis of dibenzofurans, via SNAr reaction of aryl halides and ortho-bromophenols in the presence of anhydrous K2CO 3 and subsequent ligand-free palladium-catalyzed intramolecular aryl-aryl cross-coupling cyclization under microwave irradiation, is described.

The palladium-catalyzed synthesis of dibenzofused six-membered phosphacycles via carbon-phosphorus bond cleavage is developed. This method is compatible with a range of functional groups, such as esters, amides, and carbamates, which is in sharp contrast to the limitations of the classical method using organolithium reagents.

Molecular switches based on helical tetrasubstituted alkenes, substituted with either electron-withdrawing (CF3, F, CN; 2 a-c, 3 a,c) or -donating substituents (Me, OMe; 2 d,e), have been synthesized from acyclic precursors 4 and 5 in a domino carbopalladation/Stille reaction. This palladium-catalyzed process allowed the rapid assembly of two C-C bonds, two six-membered rings, and the tetrasubstituted double bond in a completely diastereoselective fashion. The electronic effects of the substituents on the overall switching process were investigated by alternating irradiation of two different wavelength regions. Although the substituents had only a small influence on the absorption maxima, drastic differences in the switching behavior were observed. Copyright
