Electric Literature of 17261-28-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 17261-28-8, Name is 2-(Diphenylphosphino)benzoic acid, molecular formula is C19H15O2P. In a Article，once mentioned of 17261-28-8
The reaction of Na2 or with an equimolar amount of new bidentate hybrid ligands having a P and a N donor atom capable of trans chelation, o-Ph2PC6H4CH2O(CH2)nC5H4N-2 (n = 1-3), gave mainly the 1:1 complex >.Depending on the length of the backbone connecting the phosphino and the pyridyl groups, cis- or trans-co-ordinated complexes were mainly formed; when n = 1 the cis complex 1 was formed, but the ligands with longer bridges gave the trans complexes 2 and 3 respectively as the main products.From the reaction of the palladium(II) complex with o-Ph2PC6H4CH2O(CH2)nC5H4N-2 (n = 2 or 3) the trinuclear complexes 2> 4 (n = 2) and 5 (n = 3) were also obtained as minor products and the cis-chelated complexes analogous to 1 could not be isolated.The reaction of Na2 with 2 equivalents of o-Ph2PC6H4CH2O(CH2)3C5H4N-2 gave quantitatively the 1:2 complex trans-2> 7 in which the ligand is bound only through the P atom.This complex is in equilibrium with the trans 1:1 complex 3 in solution, dissociating one molecule of the ligand (Keq = 5.6 x 1E3 mol dm-3, 35 deg C).On heating in CH2Cl2-tetrahydrofuran or diethyl ether, 3 partially isomerised to the dinuclear complex 2> 6, in which the hybrid ligands act as bridges.The crystal structures of 1, 3 and 6 were determined; 3 is the first example of a transition-metal complex with a trans-spanning chelate phosphine-pyridine hybrid ligand.The reaction of the ligand o-Ph2PC6H4CH2O(CH2)3C5H4N-2 with K2, in constrast to the palladium complexes, always gave the 1:2 complex trans-2> 8 in good yield regardless of the ligand:Pt ratio.It did not dissociate in solution and the trans-chelated complex analogous to 3 could not be isolated even from the reaction of K2 with an equimolar amount of the ligand o-Ph2PC6H4CH2O(CH2)3C5H4N-2.
