Sulphonic acids RSO3H (R = CF3, CH3, or C6H4CH3-p) react with mer-, , and to afford the products , , and respectively.Under more vigorous conditions the last reaction yields the bis(sulphonate) complexes .Thelability of the monodentate sulphonate ligands has been demonstrated by the substitution reactions of with a variety of neutral donor ligands.Products readily obtained in this manner include , 2 = 2,2'-bipyridyl, 1,10-phenanthroline, ethylenediamine, or o-NH2-C6H4NH2>, and trans-.Carbonylation of affords the tricarbonyl salt whereas under similar conditions the precursors (R = CH3 or C6H4CH3-p) yield the dihydride salts .Many of the complexes isolated were solvated by H-bonded molecules of sulphonic acids.Stereochemical assignments based on ¹H, ¹⁹F, and ³¹ n.m.r. data are given for all the new products reported.
