交叉偶联 一般意义上的交叉偶联是指在过渡金属配合物的催化条件下,形成C-C键、C-het(N,O等)键, het-het键和C-X(X = Cl,Br,I 等)键的过程。 从现代有机合成化学角度来看,交叉偶联可具体分为以下两种:一是从机理上定义(mechanistic definition),二是从合成上定义(synthetic definition)。 一、机理上定义(...

Here we describe the protocol for polycondensation of bifunctional aryl ethers or aryl ammonium salts with aromatic dimetallic compounds through cleavage of inert C–O/C–N bonds. This reaction proceeds smoothly in the presence of commercially available Ni/Pd catalyst under mild conditions, affording ...
Cross-couplingrefers to the tendency of either the X- or Y-axis scanner displacement to have a fictitious Z-axis component, as shown inFig. 15(left), where,uxanduzare the voltages applied to the X- and Z-PTS[44]. The reasons for this erroneous motion are several and fairly complex; ...
