characteristics and donor/acceptor properties of a series of 2-pyridyl substituted phosphine ligands have been investigated using structural, spectroscopic and DFT calculational studies. A range of different coordination modes are observed in Mo and W carbonyl complexes of tris-2-pyridyl-phosphine ligands of the type P(2-py') (2-py' = substituted or unsubstituted 2-pyridyl group), including an unprecedented

An object of the present invention is to provide a process for efficiently producing an alkyl methacrylate. The present invention provides a process for producing an alkyl methacrylate comprising reacting carbon monoxide and an alcohol having 1 to 3 carbon atoms with methylacetylene in the presence of a catalyst comprising a Group 10 metal compound, a protonic acid and a phosphine compound, wherein the methylacetylene has a propadiene content of 50 ppm by weight or less, the use amount of the methylacetylene is 200000 mol or more based on 1 mol of the Group 10 metal compound, and the reaction is performed in the presence of water in an amount of 40000 mol or less based on 1 mol of the Group 10 metal compound.
The present invention relates to metal complexes of the formula (1) and to the use thereof in organic electroluminescent devices, and to organic electroluminescent devices which comprise these metal complexes.
