Crystal and molecular structure of a ruthenium complex containing a metalated perfluoroazobenzene ligand and a novel 2-(.eta.-cyclopentadienyl)phenyl group
“…The historically first case was observations made in connection with metalation studies at perfluorinated azobenzenes. When ruthenium complex 273 was treated with decafluoroazobenzene ( 274 ) in light petroleum at 100 °C, as a result of a C,H activation at one of the triphenylphosphane ligands, chelated complex 275 was obtained in 54% yield and characterized spectrosopically as well as by an X-ray crystal structure analysis − (Scheme ). 51 …”

The synthesis of P-functionalized molybdenum chelate complexes incorporating the linked cycloheptatrienyl− phosphane ligand [2-(diphenylphosphanyl)phenyl]cycloheptatrienyl, o-Ph 2 P−C 6 H 4 −C 7 H 6 , is described. The air-stable ligand precursor [2-(cyclohepta-2,4,6-trienyl)phenyl]diphenylphosphane (2) can be obtained in large quantities by addition of lithiated 2-BrC 6 H 4 PPh 2 (1) to the tropylium cation C 7 H 7 + . Hydride abstraction employing the trityl cation, Ph 3 C + , results in the formation of the tricyclic phosphonium salt 3. The P-functionalized cycloheptatriene 2 acts as an eight-electron ligand on reaction with Mo(CO) 6 to afford the cycloheptatriene−phosphane complex [(o-Ph 2 PC 6 H 4 -η 6 -C 7 H 7 )Mo(CO) 2 (P−Mo)] (4) as a single, chiral regioisomer, which undergoes clean hydride abstraction on treatment
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
