The first examples of a Pd-catalyzed carbonylation of aryl boronic acids with sp(3) carbon partners are presented. Various boronic acids were shown to react with 1,3-diesters and 1,3-diketones to afford structurally unique carbonyl compounds. By employing 2-substituted 1,3-diesters, synthetically-challenging quaternary carbon centres were accessed. In total, 42 examples of aryl carbonyl compoun...

Some new mononuclear complexes [ML1L2(NO3)2 ] {where M = [Co(II), Ni(II), Cu(II) and Zn(II)], L1 = 2Hydroxy-5-nitrobenzaldehyde and L2 = diketones (Pentane-2,4-dione, 1-phenylbutane-1,3-dione, 1,3diphenylpropane-1,3-dione)}, have been synthesized and were characterized by elemental analysis, molar conductance, , FTIR spectra, UV, magnetic moment and thermo gravimetric analysis (TGA). The relati...

A simple and convenient one-step method for synthesis of acridines and their derivatives from condensation of aromatic aldehydes, cyclic diketones, and aryl amines using Cu-doped ZnO nanocrystalline powder as a catalyst is reported. The present protocol provides several advantages such as good yields, short reaction time, easy workup, and simplicity in operation.

This review aims to give an overview of the current status of our research on the synthesis of π-electron donor bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF, ET) analogues prepared from 1,8-diketones via a ring forming reaction. The new synthesized π-electron donors have vinyl moieties producing extended π-electron delocalization over the substituent phenyl rings at the peripheries.

A new type of TfOH-catalyzed tandem cyclopropane ring enlargement/C-C formation/etherification reaction between alkynylcyclopropanes and 1,3-diketones to cyclobutane-fused dihydrofurans is described. The reaction tolerates a range of aryl and alkyl substituents with moderate to good yields.
