During the past years, the interest in complexes of transition metals with organophosphorus ligands has been growing considerably in the light of their versatile applications in coordination chemistry and homogenerous catalysis. The palladium system has good prospects in the catalytic application. Particularly for a lack of selectivity under classic conditions or for base sensitivity of the functional groups, transition metal catalysis under mild and neutral conditions offers a promising and superior alternative. A (1, 2-diaryl)vinylphosphine ligand has one aryl group at the α-position and one aryl group at the β-position, respectively. The ligand more steric hindrance and electron-richness around the phosphorus atom was synthesized. Complex of palladium-(1, 2-diaryl)vinylphosphine as a catalyst shows highly catalytic activity in Sonograshira cross coupling reaction.

Basing on the Karamata regular variation theory and combining with the method of explosive sub and supersolution, we establish the asymptotic behavior of large solutions to a quasilinear elliptic equation type with convection terms. the nonlinear term is Γ-varying at infinity, which variation at infinity is not regular. The results of this paper emphasizes the central role played by the convection term and the weight functions. © 2011 Springer-Verlag.

A new fuzzy recognition method of machine-printed invoice number based on neural network is presented. This method includes ten links: invoice number detection and separation of right on top of invoice, binarization, denoising, incline correction, extraction of invoice code numerals, window scaling, location standardization, thinning, extraction of numeral feature and fuzzy recognition based on BP neural network. Through testing, the recognition rate of this method can be over 99%.The recognition time of characters for character is less than 1 second, which means that the method is of more effective recognition ability and can better satisfy the real system requirements. © (2012) Trans Tech Publications, Switzerland.
