The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), molecular formula is C39H32OP2.

Abstract Reaction of [Cu(N?CCH3)4]ClO4 with 3,8-dibromo-1,10-phenanthroline (BrphenBr) or 5,5?-dibromo-2,2?-bipyridine (BrbpyBr) and diphosphine ligands (±)-2,2?-bis(diphenylphosphino)-1,1?-binaphthalene (BINAP) or 9,9-dimethyl-4,5-bis(diphenylphosphino)-9H-xanthene (xantphos) in dichloromethane produced four mononuclear Cu(I)-diimine-diphosphine complexes in good yields. All structures are characterized by single crystal X-ray structure analysis, elemental analysis, electrospray ionization mass spectra, 1H NMR and 31P NMR spectra. All complexes are very stable to air and moisture in the solid state. The existence of soft P donors, the chelating effect of P and aromatic N atoms and the high-level protection of all the Cu(I) centers resulting from the close contact of bromodiimine and diphosphine ligands are suggested to be responsible for such stability. All complexes display moderate emission behavior in the solid state.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), you can also check out more blogs about161265-03-8
