Electric Literature of 161265-03-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), molecular formula is C39H32OP2. In a Article，once mentioned of 161265-03-8
Reaction of [Cu(MeCN)4]ClO4with 1H-imidazo[4,5-f][1,10]phenanthroline derivatives (L1, L2 and L3) and the bulky, rigid chelating diphosphine ligand 9,9-dimethyl-4,5-bis(diphenylphosphino)-9H-xanthene (xantphos) under alkaline conditions in different ratios afforded a series of luminescent binuclear [Cu2(L?H)(xantphos)2]ClO4(L = L1, 1a; L2, 2a; L3, 3a) and trinuclear [Cu3(L?2H)(xantphos)3]ClO4(L = L1, 1b; L2, 2b; L3, 3b) complexes. Both trigonal planar and tetrahedral coordination modes of Cu(I) centers were observed for complexes 1a and 1b, and they exhibit obvious C[sbnd]H?Cu agostic or anagostic interaction for the trigonal planar Cu(I) centers. The31P NMR, electronic absorption and emission spectra are discussed. All the complexes exhibit weak luminescence at room temperature in the solid state and in the solution.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 161265-03-8 is helpful to your research., Electric Literature of 161265-03-8
