Quality Control of Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II). Introducing a new discovery about 887919-35-9, Name is Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II)
The invention relates to provide a following formula (III) shows the alkyne base by the substituted pyrrole compound synthesis method, the method comprising: under the nitrogen atmosphere, sequentially to the organic solvent in the ball point pen (I) compounds, of formula (II) compound, catalyst, organic ligand, alkali and accelerator, in the 50 – 70 C stirring for 4 – 8 hours, after treatment of the compound of formula (III) Wherein R1 C selected from1 – C6 Alkyl or phenyl; R2 Is selected from H, C1 – C6 Alkyl or halogen; R3 C selected from1 – C6 Alkyl or benzyl; R4 Is selected from H, C1 – C6 Alkyl, cyano or halogen; X is halogen. The method through the catalyst, organic ligand, alkali, organic solvent of the accelerator and the comprehensive selective coordination with the, thus can yield to obtain the target product, for this kind of compound synthesis provides new method, in the organic synthesis especially medical intermediate synthesis technological field has good application prospect and industrial production potential.
