Phosphines nitrosyls

As indicated above, the antiknock effect is shown by many compounds. Outstanding among these are the organometallic compounds of many metals. Effective derivatives of many metals include alkyl compounds, aryls, carbonyls, nitrosyls, phosphines, cyclopentadienyls, and many mixed compounds. The aromatic amines are also good antiknock agents, but far less effective than the organometallic compounds. The reason why commercialization efforts were concentrated on tetraethyllead early in the history of antiknock investigations is evident from Table 1, which is a composite of early data 6 8,216). 

Alkyl, aryl and acyl nitrosyl phosphines and hydridophosphine complexes of Ru11 are covered in Sections 45.5.4.6.iii and 45.10 respectively. 

As a rule, the formation of macromolecular metallocomplexes include a special design of macroligand, their functional groups, and MX with its own and frame ligands, which are retained in the inner coordination sphere of metal after immobilization. In addition to the halides, carbonyls, nitrosyls, phosphines, acetylacetonates and CH3COO-, pyridine and Dipy can also be used as frame ligands [35]. 

Codeposition of silver vapor with perfluoroalkyl iodides at -196 °C provides an alternative route to nonsolvated primary perfluoroalkylsilvers [272] Phosphine complexes of trifluaromethylsilver are formed from the reaction of trimethyl-phosphme, silver acetate, and bis(trifluoromethyl)cadmium glyme [755] The per-fluoroalkylsilver compounds react with halogens [270], carbon dioxide [274], allyl halides [270, 274], mineral acids and water [275], and nitrosyl chloride [276] to give the expected products Oxidation with dioxygen gives ketones [270] or acyl halides [270] Sulfur reacts via insertion of sulfur into the carbon-silver bond [270] (equation 188)... 

Study of the nitrosyls Ru(NO)X3(PR3)2 shows that their photochemical behaviour depends on the tertiary phosphine (Figure 1.44). 

Phosphine complexes like OsN(PMe3)2(R2)Cl (R = CH2SiMe3) with chloride tram to nitride, and frans-phosphines and iraras-alkyls, have been made [191]. Me3NO (but not Ph3PO or C5H5NO) oxidizes a nitride group into a nitrosyl... 

Nitrosyl is now well established as a ligand for low-valent cobalt. The distorted tetrahedral [Co(NO)2(py)2]+ has been prepared and structurally characterized.132 In contrast to bis-phosphine... 

The nitrosyls RuH(NO)(PR3)3 are 5-coordinate with trigonal bipyramidal structures and linear Ru-N-O geometries the hydride and nitrosyl ligands occupy the apical positions (for RuH(NO)(PPh3)3, z/(Ru-H) 1970 cm-1, i/(N—O) 1640 cm-1 H NMR, 8 = +6.6 ppm for the hydride resonance). The high-field NMR line is a quartet showing coupling with three equivalent phosphines, which would not be possible in a square pyramidal...
