Metal Isocyanide Complexes

摘要: Publisher Summary This chapter discusses metal–isocyanide chemistry. In the interim, reviews have appeared on specific aspects of isocyanide The generally accepted valence bond and molecular orbital (MO) approach to bonding metal isocyanides has been well described in Treichel's review, used rationalize variations infrared (IR) stretching frequencies between bonded nonbonded better π-acceptor qualities aryl versus alkyl groups. A number new synthetic routes complexes chromium, molybdenum, tungsten investigated. attempts made over years develop reproducible six- seven-coordinate molybdenum tungsten. employed for synthesis by generating ligand atom. monomeric prepared, which may be considered as substitution products [Co(CNR) 5 ] + [M(CNR) 4 cations. Electrochemical investigations reported a range homoleptic mixed carbonyl–isocyanide complexes, substituent effects with electronic structure metal. Insertion reactions isonitriles into metal–alkyl or metal–aryl bonds are now established, occurring –aryl groups from group IVA IB and, recently, uranium thorium carbon bonds.
