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. 213697-53-1, C26H36NP. A document type is Patent, introducing its new discovery., SDS of cas: 213697-53-1
The invention discloses a novel monophosphine ligand preparation method. The process of the method is: a) to commercialization of biphenyl, pyrrole, yinyin duo or polymerization catalyst monophosphine ligand as raw materials, under protection of inert gas, in the organic solution, the participation of the inorganic base, to control the reaction temperature 70 – 150 C, raw materials with aromatic halogenated object through the price rhodium catalytic guide hydrocarbon activation reaction for the preparation of aryl-substituted biphenyl, pyrrole, or polymerization catalyst yinyin duo novel monophosphine ligand. This synthetic route has not seen the literature reports, and the cost of raw material; unit of simple operation, low equipment requirements, is suitable for the rapid construction of model monophosphine ligand library.
