Synthesis and characterization of soluble polycationic ruthenium polystyrene derivatives [PSTRuL]CF3SO3, (L = C5Me5, Ru:[PhC2H3]= 0.5 : 1; L = C8H11, Ru:[PhC2H3] > 0.9 : 1) and [PSTRuH(PCy3)2]CF3SO3[PST = polystyrene, PCy3= P(c-C6H11)3

Abstract

Protonation of the ruthenium derivatives Ru(COD)(COT)(COD = 1,5-C8H12, COT = 1,3,5-C8H10), [(η5-C5Me5)RuOMe]2, and RuH2(H2)2(PCy3)2[PCy3= P(c-C6H11)3] in the presence of polystyrene leads to the polymeric materials [PSTRu(η5-C8H11)]CF3SO3(4), [PSTRu(η5-C5Me5)]CF3SO3(2), and [PSTRuH(PCy3)2]CF3SO3(7) in which the ruthenium fragments are bonded to over 90, 50, and 25%, respectively, of the phenyl rings of polystyrene; compounds (2) and (4) are air-stable, soluble in acetone and methanol, and have been characterized by microanalytical and spectroscopic methods; (7) is slightly air-sensitive and has been characterized by comparison with [(η6-PhMe)RuH(PCy3)2]BF4(6).
