Efficient and high turnover homocoupling reaction of aryl iodide by the use of palladacycle catalyst. A convenient way to prepare poly-p-phenylene

Abstract Monoiodoarenes undergo reductive coupling to produce biaryls in high yields in the presence of less than 0.1 mol % of palladacyle and N , N -diisopropylethylamine in DMF at 100°C. Under similar reaction conditions, p -diiodobenzene produces poly- p -phenylene in greater than 85% isolated yields.

Simple transformation of nitrile into ester by the use of chlorotrimethylsilane

Abstract Treatment of nitriles with alcohol and chlorotrimethylsilane at 50°C for 4 h could give esters in fair to good yields. Under similar reaction conditions, intramolecular lactonization via the concomitant nitrile and hydroxy groups in good yield were also demonstrated.

Indium-mediated tandem dimerization and cyclization of nitrqones and aldimines to 3-arylaminodihydrobenzofurans under aqueous conditions

Abstract Nitrones undergo deoxygenative reductive coupling and subsequent cyclization to 3-arylamino-2,3-dihydrobenzofuran derivatives in the presence of indium under aqueous conditions at ambient temperature in good yields.

A novel palladium-catalyzed tandem dimerization and cyclization of acetylenic ketones. A convenient method for 3,3′-bifurans

Abstract Alkynones undergo rearrangement in the presence of Pd(PPh 3 ) 4 and triethylamine in tetrahydrofuran at room temperature to give 2,5-substituted furans, but under similar conditions PdCl 2 (PPh 3 ) 2 , by a tandem dimerization and cyclization, gives 3,3′-bifurans predominantly.

Indium-Mediated Deoxygenation of Nitrones, N-Oxides and Deoxygenative Reductive Coupling of Nitrones to Vicinal Diamines

Abstract We reported transformation of nitrones selectively either to aldamines or vicinal diamines and deoxygenation of N-oxides using Indium at ambient temperature in good yields.

A novel palladium-catalyzed cyclization of β-iodo-β,γ-enones toward 2,5-disubstituted-furans

Abstract The use of palladacycle catalyst to the transformation of various (Z) -β-iodo-β,γ-enones into the corresponding 2,5-disubstituted furans in good yields at room temperature was described. The comparison of using other kind of palladium catalysts under the similar reaction conditions was also described.
