Reference of 52409-22-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 52409-22-0, Pd2(DBA)3, introducing its new discovery.
The invention relates to a pyrrole as shown in the following formula (IV) and catalytic synthesis of indole compounds, The method comprises: at the room temperature and under the nitrogen atmosphere, sequentially adding to the organic solvent in the following formula (I) compound, the compound of formula (II), the following formula (III) compound, composite catalyst, gallium trichloride, organic ligand and organic alkali, then heating to 70-85 C and thermal insulation fully stirring reaction 4-6 hours, then after processing by said formula (IV) compound; wherein R 1 is selected from H or C 1-C 6 alkyl; R 2 selected from H, C 1-C 6 alkyl, C 1-C 6 alkoxy or halogen; R 3 is selected from H or halogen; X is halogen. The method, through suitable reaction substrate, catalyst, organic ligand, organic base and organic solvent and comprehensive selective synergistic, through the use of gallium trichloride and, thus can yield to obtain the target product, in the field of the synthesis of pharmaceutical intermediates with good application prospect and broad market promotion value.
