Cooperative bimetallic oxidative addition reactions*
The factors that control the oxidation of metals in bimetallic complexes are investigated in relation to the possibility of developing one-site addition two-metal oxidation reactions such as those that occur in the respiratory protein, hemerythrin. It is shown that the behavior of bimetallic complexes is not represented by the sum of the analogous monometallic parts because of metal and ligand ...
متن کاملLewis acid-promoted oxidative addition of thioimidates to Pd0.
The isomeric S-methyldihydropyrrins 9-Z and 9-E exhibit markedly different behavior in Pd(0)-catalyzed cross-coupling reactions. Thioimidates 9-Z are readily converted to imines 10-Z employing Pd(0)/AlkZnI. Under identical conditions 9-E are inert. Oxidative addition to Pd(0) requires activation by Zn or other Lewis acids, which is sterically unfavorable with 9-E. Analogous results were obtaine...
متن کاملOxidative Addition of Pseudohalogen to [P(OPh)3]4Ni
Z. Naturforsch. 38b, 1069-1071 (1983); received May 13, 1983 Pseudohalogens, IR Spectra, Nickel The title compound reacts with cyanogen halides, XCN (X = Br or I) to give the complexes L2(X)(CN)Ni (L = P(OPh)3, X = Br or I). The oxidative addition of (SCN)2 and (SeCN)2 to the same compound results in the formation of L2Ni(XCN)2 (X = S or Se). All the complexes have been characterized by element...
متن کاملHalobenzenes and Ir(I): kinetic C-H oxidative addition and thermodynamic C-Hal oxidative addition.
A (PNP)Ir fragment undergoes facile, room-temperature oxidative addition of C-H bonds in arenes and haloarenes in preference to aromatic carbon-halogen bonds. This preference, however, is determined to be kinetic in nature. Oxidative addition of C-Cl and C-Br is preferred thermodynamically. The products of the C-Cl or C-Br oxidative addition are separated from the C-H oxidative addition product...
متن کاملP-97: The Effects of Catalase Addition to The Cryopreservation Medium on Follicles Apoptosis and Oxidative Stress in Human
Background Today, cryopreservation of ovarian tissue has been the effective procedure to restore fertility in can cer patients. It is well known that oxidative stress (OS) is a widespread phenomenon that occurs in ovary cryopreservation. Numerous studies show that follicular atresia in mammalian species due to the accumulation of toxic metabolites often results from oxidative stress. Therefore,...
