Further MS(FD) investigations of CpRu(eta6-C6H5)BPh3 have revealed under increased heating current of the field ion emitter the next set of signals centered at m/e 652.To account for this phenomenon, the formation of the dinuclear <(CpRu(eta6-C6H5))2BPh2>+ cation containing two Cp rings, is proposed.The rearrangement of CpRu(eta6-C6H5)BPh3 into a new ion-pair with <(CpRu(eta6-C6H5))2BPh2>+ cation is also observed in high-boiling point media, such as ethylene glycol.The ion-pair with the tetraphenylborate anion (yield 35percent), has been isolated from the reaction.The duration of refluxing was extremely long (100-700 hours).The new ion-pair with BPh4- anion is stable and its MS(FD) spectrum shows only the set of signals centered at m/e 652.The mechanism for the synthesis CpRu(eta6-C6H5)BPh3 and its novel complex cation and their MS(FD) investigations are presented.

Diastereomerically pure complexes of formula CpRuCl(PP*) and CpRuH(PP*) with chiral ferrocenyl diphosphines were prepared and the selectivity of proton-transfer processes over the monohydride compounds with different acids was studied. With 1 equiv of HBF4 the cis-dihydrogen and trans-dihydride complexes were formed while with 3 equiv of CF 3CO2H the trans-dihydride derivative was the only product. However, the use of 1 equiv of CF3CO2H led to a dihydrogen bonded complex with an extremely short RuH…HO 2CF3 interaction that exhibits proton-hydride exchange. Using the labeled acid CF3CO2D, a stereoselective transference of the deuteron was demonstrated that implies the previous epimerization of the monohydride and the subsequent attack of the acid in the position previously occupied by the hydride.

The preparation of several ruthenium complexes containing cyanocarbon anions is reported. Deprotonation (KOBu?) of [Ru(NCCH2Ph3)2Cp]PF6 (1) gives Ru{N=C=CH(CN)}(PPh3)2Cp (2), which adds a second [Ru(PPh3)2Cp]+ unit to give [{Ru(PPh3)2Cp}2 (mu-NCCHCN)]+ (3). Attempted deprotonation of the latter to give the mu-NCCCN complex was unsuccessful. Similar chemistry with tricyanomethanide anion gives Ru{N=C=C(CN)2} (PPh3)2Cp (4) and [{Ru(PPh3) 2Cp} 2 {mu-NCC(CN)CN}]PF6(5), and with pentacyanopropenide, Ru{N=C=C(CN)C(CN)C(CN)2} (PPh3)2Cp (6) and [{Ru(PPh3)2Cp}2 {mu-NCC(CN)C(CN)C(CN)CN}]PF6 (7). The Ru(dppe)Cp* analogues of 6 and 7 (8 and 9) were also prepared. Thermolysis of 6 (refluxing toluene, 12 h) results in loss of PPh3 and formation of the binuclear cyclic complex {Ru(PPh3) Cp[mu-N=C={C(CN)=C(CN)2}CN]}2 (10). The solid-state structures of 2-4 and 8-10 have been determined and the nature of the isomers shown to be present in solutions of the binuclear cations 7 and 9 by NMR studies has been probed using Hartree-Fock and density functional theory.
