Silver organometallic compounds

Organometallic compounds of silver [2(f), 6] are restricted to the silver(I) state and are usually light, air and moisture sensitive. Simple alkyls are unstable at room temperature though some fluoroalkyls are isolable. Therefore, perfluoroisopropylsilver is stable to 60°C as a MeCN adduct. Alkenyls... 

Thia-crown ethers incorporating propan-2-one units and dimeric silver(I) compounds as (176) and other polymeric species have been prepared.1132,1133 Other substituents can be diisopropyl idene groups which form complexes of the type [AgL(PPh3)]OTf (177),1134 pyridazine,1133 phthalazine1136 ligands or even organometallic compounds as ferrocene in (178).1137... 

The most systematic study of reactions of transition metal atoms with halogen compounds has been the work of Klabunde on oxidation of nickel and palladium atoms. Some work has been done with copper, silver, gold, and platinum, but only scattered results have been reported for other metals. Klabunde s research has shown that perfluoroorgano-halides form isolable organometallic compounds on reaction with metal atoms much more commonly than nonfluorinated halides. The types of reactions observed with different classes of organic halides are considered next. 

There are strong similarities between the organometallic compounds of copper and silver. The simple alkyl complexes AgR are thermally unstable. The stability... 

Silver alkyls and aryls, together with silver(I) complexes of cyclic polyenes and aUcynyl ligands, are generally classified under organometallic compounds. Stable silver(l) carbonyl complexes that have been characterized by X-ray analysis include [Ag(CO) B(OTeF5)4 ], [Ag(CO)2 B(OTeF5)4 ], and [Ag(CO) HB[3,5-(CF3)2pz]3 ]. Silver acetylide (AgzCz) complexes are described in Section 3.6.
