Chemistry involves the study of all things chemical – chemical processes, Formula: C12H3Fe, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. In a patent，Which mentioned a new discovery about 1271-51-8
The invention discloses a chiral ferrocenesulfonic such P, P method for synthesizing of the ligand, belonging to the field of organic synthesis. This method is realized by the following steps : (1) with vinyl ferrocene as the starting material, chiral under the action of catalyst, and the two disclosed reaction to obtain (R) -1 the […] ferrocenesulfonic yl group II alkyl phosphine ; (2) (R) -1 the radicals […] ferrocenesulfonic yl acetate is disclosed and diethyl zinc reaction and the diphenyl phosphine reaction to obtain the chiral ferrocenyl such P, P ligand (R)-(-) – 1 the […] [(S) -2 the […] (mortars; concrete ; artificial stone) ferrocene] ethyl b is disclosed. Compared with the prior art, the present invention of fewer steps, the operation is simple, high yield, is more suitable for industrial production. Such chiral ferrocenyl made of P, P compounds can be used as the ligand of metal catalyst, used in the medical field. (by machine translation)
