Formation as a catalyst of copper carbon-carbon bond between - carbon and heteroatom between - carbonThe present invention provides a method represented by Scheme 1: wherein X represents I, Br, Cl, alkylsulfonate, or arylsulfonate; Z represents optionally substituted aryl, heteroaryl or alkenyl; ...
Carbon fibre-reinforced polymer (CFRP) bars are currently used to reinforce concrete in an attempt to overcome the corrosion issue encountered with ordinary steel. In order to exploit more efficiently their tensile capacity, it is interesting to use CFRP bars as prestressing tendons. This application...

Insertion of Imines into Palladium–Acyl Bonds: Towards Metal-Catalyzed Alternating Copolymerization of Imines with Carbon Monoxide To Form Polypeptides From a methyl ligand, CO, and an imine a chelating amide ligand is formed by insertion of the C=N bond into the metal–acyl bond in cationic pa...
Motivated by the growing interest in the grafting of conducting surfaces and seeking a rationale to explain the differences in electron transfer rates measured in recent experiments, we apply density functional theory to shed light on the binding of carbon to gold. A comparative study between the ...

The C−C bond cleavage of terminal and internal diynes takes place readily in the presence of catalytic amounts of Ru3(CO)12 or Pd(NO3)2 and of 2-aminophenol, giving the corresponding benzoxazoles and ketones in good to high yields. There are two different modes of the bond cleavage:...
