Polyaniline-anchored palladium catalyst-mediated Mizoroki-Heck and Suzuki-Miyauraa reactions and one-pot Wittig-Heck and Wittig-Suzuki reactions

A polyaniline-anchored palladium catalyst was prepared and screened for coupling reactions of aryl halides. The robust and recyclable catalyst was effective in Mizoroki-Heck and Suzuki-Miyaura reactions of aryl bromides and aryl iodides. The catalyst system was further employed for one-pot Wittig-Heck and Wittig-Suzuki combinations to build conjugated compounds in good conversions.

Gold(I) styrylbenzene, distyrylbenzene, and distyrylnaphthalene complexes: High emission quantum yields at room temperature

One gold(I)-substituted styrylbenzene, six digold(I) distyrylbenzenes, one tetragold distyrylbenzene, and four digold distyrylnaphthalene complexes were synthesized using base-promoted auration, alkynylation, triazolate formation, and Horner-Wadsworth-Emmons reactions. The gold(I) fragments are either σ-bonded to the aromatic system, or they are attached through an alkynyl or triazolate spacer. Product formation was monitored using 31P{ 1H} NMR spectroscopy. Systems in which gold(I) binds to the central benzene ring or the terminal phenyl rings were designed. All of these complexes have strong ultraviolet absorptions and emit blue light. The position of the gold(I) attachment influences the luminescence efficiency. Complexes with two gold(I) fragments attached to the ends of the conjugated system have fluorescence quantum yields up to 0.94, when using 7-diethylamino-4- methylcoumarin as the emission standard. Density-functional theory calculations on three high-yielding emitters suggest that luminescence originates from the distyrylbenzene or -naphthalene bridge. Copyright

A convenient one-pot synthesis of bis[(E)-4-halostyryl]arene derivatives

A new convenient synthetic protocol for the one-pot stereoselective synthesis of bis[(E)-4-bromo(or chloro)styryl]arene derivatives via the sequential reaction of silylative-coupling of 4-halostyrenes with vinylsilanes followed by palladium-catalyzed cross-coupling 4-halostyrylsilanes with diiodoarenes, is described. The reaction leads to symmetrical bis[(E)-4-halostyryl]arene derivatives obtained in a stereocontrolled manner with high efficiency. Georg Thieme Verlag Stuttgart.

Palladium-catalyzed stereoselective synthesis of (E)-stilbenes via organozinc reagents and carbonyl compounds

In the presence of a catalytic amount of PdCl2(PPh 3)2 and a silylating agent, organozinc halides reacted with carbonyl compounds to give the corresponding (E)-stilbenes in good to excellent yields under mild conditions. The reaction mechanism is briefly discussed.
