Application of 12150-46-8, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 12150-46-8, C34H28FeP2. A document type is Patent, introducing its new discovery.
The invention discloses a method for preparing ferrocene diphosphine ligand, and belongs to the field of organic synthesis. The method comprises the following steps: by taking ferrocene as an initial raw material and boron trifluoride diethyl etherate as a catalyst, reacting with diaryl phosphine oxide or dialkyl phosphine oxide, hydrolyzing so as to obtain tertfluoborate of a ferrocene diphosphine compound, and performing heating backflow deprotection in methanol, thereby obtaining the ferrocene diphosphine compound. Compared with the prior art, the method is gentle in reaction condition, simple in aftertreatment, and relatively applicable to industrial production, and the yield is greater than 90%. The prepared ferrocene diphosphine can be used as ligand of a metal catalyst, and can be used in the fields such as organic optoelectronic materials and medicines.
