Application of 32993-05-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a patent, introducing its new discovery.
It was surprisingly found that the highly active allyl alcohol redox isomerization catalyst [RuCp(PPh3)2](OTs) upon addition of a catalytic amount of a strong acid can change its catalytic action fully to the selective O-allylation of phenols with allyl alcohol. High turnover numbers (75,000 based on phenol; 200,000 based on allyl alcohol) are reached, and the catalyst is very stable in the presence of substrate. Addition of triphenylphosphine to the reaction mixture does not lead to further stabilization of the catalyst; instead, the free phosphine is rapidly allylated, thereby consuming the acid, which deactivates the catalytic system for allylation reactions. This catalyst with monodentate phosphine ligands is superior in both activity and selectivity to similar catalysts with bidentate phosphine ligands. Apart from phenols, also thiophenol can be efficiently allylated to form allyl phenyl sulfide.
