Phenyl rings, orthometalation

Another important class are those obtained by orthometallation of phenyl rings, as in the following general reaction ... [Pg.676]

The metallation of -hybridized carbon atoms is more facile than that of sp3-C the reaction of phenyl rings is known as orthometallation. Some... [Pg.1198]

Recently, Peris and coworkers reported the synthesis of highly stable orthometallated Cp -Ir NHC complexes and a catalytic application in the deuteration of organic molecules. Complexes (227) were synthesized from imidazolium salt (225) and [IrCp Cl2]2 as metal precursor either by a one-step procedure with sodium iodide to minimize the mixture I versus Cl or by transmetallation from the corresponding silver carbene affording (226) followed by the C-H activation of the phenyl ring by the iridium... [Pg.6641]

Heating Pt(OH)CH3(Ph2PCH2CH2PPh2) in methanol results in reduction and orthometallation of one of the phenyl rings to give Pt2(/t-o-C6H4P(Ph)CH2CH2PPh2)2 with a short (2.628 A) Pt-Pt bondT... [Pg.200]

The compound Fe(CO)3 P(OPh)3)2 undergoes orthometallation of one of the phenyl rings with loss of CO. This process is reversible upon addition of an isocyanide ligand to give a substituted bis(phosphine)-bis(carbonyl) complex (Scheme SS). ... [Pg.49]
