          Abstract

          Reaction of dinuclear complex [{(h6-C6Me6)Ru(µ-Cl)Cl} 2] with the ligand NH(PPh2)2 in 1:2 molar ratio affords the mononuclear complex [(h6-C6Me6)RuCl 2{h1-(PPh2)2NH}](1) which in turn reacts with AgPF6 to yield the cationic compound [(h6-C6Me6)RuCl{h 2-(PPh2)2NH}]PF6 (2). Complex 3 reacts with KOBut to give the neutral complex [(h6-C6Me6)RuCl{h 2-(PPh2)2N}](3). The anionic ligand of complex 3 reacts easily with HBF4 regenerating the starting complex and with MeI by N-methylation of the chelate ligand. The non coordinating P atom of complex 1 reacts with sulfur or selenium to form the P-coordinate monosulphide or selenide ligands, [{(h6-C6Me6)RuCl 2{h1PPh2NHP(E)Ph2 }] (5,6). The treatment of complexes 5 and 6 with AgPF6 affords cationic (7,8) or neutral (9,10) complexes depending of the solvent used. The neutral complex 9 can be N-derivatized by reaction with MeI

          La reacción del complejo dinuclear [{(h6-C6Me6)Ru(µ-Cl)Cl} 2] con el ligando NH(PPh2)2 en relación molar 1:2 genera el complejo mononuclear [(h6-C6Me6)RuCl 2{h1-(PPh2)2 NH}](1), el que posteriormente reacciona con AgPF6 formando el complejo catiónico [(h6-C6Me6)RuCl{h 2-(PPh2)2NH}]PF6 (2). El complejo 2 reacciona con KOBut con formación del complejo neutro [(h6-C6Me6)RuCl{h 2-(PPh2)2N}](3). El ligando aniónico del complejo 3 reacciona facilmente con HBF4 regenerando el complejo de partida y con MeI a través de la metilación del átomo de nitrógeno del ligando coordinado. El átomo de fósforo no coordinado del complejo 1 reacciona con azufre o selenio con formación del ligando coordinado monosustituído,[{(h6-C6 Me6)RuCl2{h1PPh 2NHP(E)Ph2}] (5,6). El tratamiento de los complejos 5 y 6 con AgPF6 conduce a la formación de compuestos catiónicos (7,8) o neutros (9,10) dependiendo del tipo de disolvente utilizado. El atomo de nitrógeno del complejo neutro 9 puede ser derivatizado por reacción con MeI
