Complexes 6-arene)1-Ph2PCH2C=O)OR>RuCl2> have been prepared.Easy methanolysis and hydrolysis of the ester function occur when R=t-Bu.When R=Me, the stability of the ester function allows the synthesis of the stable salts 6-arene)2-Ph2PCH2C(=O)OMe>RuCl>X (X=PF6 or BF4).Preparation of 6-arene)(L)1-Ph2PCH2C(=O)OMe>RuCl>+ (L=Me2S, MeCN or t-BuCN) from η1-P- and η2-(P,O)-methyl phosphinoacetate derivatives has been studied and the strength of both the L and ester ruthenium coordinative bonds compared.The reactivity of these functional phosphine complexes differs markedly from that of the homologous compounds 6-arene)(PMe3)RuCl2>,6-arene)RuCl2> and 6-arene)2-Ph2PC(R)=C(R')O>RuCl.Competitive and reversible coordination of dimethylsulfide and nitriles or of the ester function is observed and a change in the arene produces selectivity in the coordination of dimethylsulfide and nitriles.Key words: Ruthenium; Iron; Phosphine; Arene
