Half-sandwich cyclopentadienyl ruthenium complexes of achiral and chiral diphosphazanes
Reaction of [CpRu(PPh3)2Cl] (1) {Cp = eta5-(C5H5)} with X2PN(CHMe2)PYY? {X = Y = Y? = Ph (L1); X = Y = Ph, Y? = OC6H4Me-4 (L4); X = Y = Ph, Y? = OC6H3Me2-3,5 (L5); X = Y = Ph, Y? = N2C3HMe2 (L6)} yields the cationic chelate complexes, [CpRu(eta2-(X2PN(CHMe2)PYY?))PPh3 ]Cl. On the other hand, the reaction of 1 with X2PN(CHMe2)-PYY? {X2 = YY? = O2C6H4(L2)} gives the complex, [CpRu(eta1-L2)2PPh3]Cl. Both types of complexes are formed with X2PN(CHMe2)PYY? {X = Ph, YY? = O2C6H4 (L3)}. The reaction of 1 with (R),(S)-(H12C20O2)PN(CHMe2)PPh2 (L7) yields both cationic and neutral complexes, [CpRu{eta2-(L7)}PPh3]Cl and [CpRu{eta1-(L7)}2PPh3]Cl and [CpRu{eta2-(L7)}-Cl]. The reactions of optically pure diphosphazane, Ph2PN(*CHMePh)PPhY (Y = Ph (L8); Y = N2C3HMe2-3,5 (L9)) with 1 give the neutral and cationic ruthenium complexes, [CpRu{eta2-(Ph2PN(R)PPhY)}Cl] and [CpRu{eta2-(ph2PN(R)-PPhY)}PPh3]Cl. “Chiral-at-metal” ruthenium complexes of diphosphazanes have been synthesized with high diastereo-selectivity. The absolute configuration of a novel ruthenium complex, (SCSPRRu)-[(eta5-C5H 5)Ru* {eta2-(Ph2PN(*CHMePh)-P*Ph(N2C 3HMe2-3,5))}Cl] possessing three chiral centers, is established by X-ray crystallography. The reactions of [CpRu{eta2-(L8)}Cl] with mono or diphosphanes in the presence of NH4PF6 yield the cationic complexes, [CpRu{eta2-(L8)}{eta1-(P)}]PF6 {P = P(OMe)3, PPh3, Ph2P(CH2)nPPh2 (n = 1 or 2)}.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), you can also check out more blogs about32993-05-8
