Arenediazonium complexes of cobalt(I): synthesis and properties

Abstract

Arenediazonium complexes of cobalt(I) of the type [Co(RN2)L4][BPh4]2[L = P(OEt)2Ph, P(OEt)3, or P(OMe)3; R = 4-CH3C6H4, 3-CH3C6H4, 2-CH3C6H4, C6H5, 4-CH3OC6H4, 4-ClC6H4, or 4-FC6H4] have been prepared; their characterization by i.r., 1H, and 31P-{1H} n.m.r. spectra is reported. Reactivity with π-acceptor ligands such as CO, NO, isocyanide, and phosphite is also described. Finally, the reaction of the arenediazonium complexes with chloride ions affording the cobalt(II) derivatives [CoClL4]+ has been investigated; the function of RN2 as an oxidizing agent in this reaction is also discussed.
