Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), Application In Synthesis of (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine).
A pharmaceutical intermediate between three aryl of compounds of synthetic method (by machine translation)
The invention relates to a kind of the following formula (III) by three shows method for synthesis of aryl of compounds, said method comprising: in the organic solvent, the catalyst, organic ligand, in the presence of alkali and accelerator, the following formula (I) compounds of the formula (II) compound to carry out the reaction, after-treatment after the reaction, so as to obtain states the type (III) compound, Wherein R1 Is H, C1 – C6 C alkyl or1 – C6 Alkoxyl; R2 – R3 Are each independently selected from H, C1 – C6 Alkyl, C1 – C6 Alkoxy or halogen; X is halogen; M is an alkali metal atom. The method through a specific reaction substrate, and through catalyst, organic ligand, alkali and accelerator integrated in coordination with and promote each other, thus to a high yield of the objective product, for this kind of compound synthesis provides a new method, and has good promotion value and application prospect.
