Synthesis of ferrocenyldiimine metal carbonyl complexes and an investigation of the Mo adduct encapsulated in cyclodextrin

New Journal of Chemistry (2004)

Željko Petrovski Susana S. Braga Sandra Rodrigues Cláudia C. L. Pereira Isabel S. Gonçalves

Cr and Mo tetracarbonyl complexes bearing the diimine ligand N,N′-bis(ferrocenylmethylene)ethylenediamine (FcNN) have been prepared from the ligand and M(CO)6. Two isomeric forms of (FcNN)Mo(CO)4, corresponding to the cis,cis and cis,trans geometries with respect to the CN bonds of the free ligand, were shown to exist in a 1∶12.5 ratio by 1H NMR (NOE experiments). By contrast, only the trans,trans isomer is observed for the Cr complex (FcNN)Cr(CO)4. The compounds (FcNN)M(CO)4 show ferrocene-based irreversible oxidation processes that lead to the deposition of a film at the electrode surface. (FcNN)Mo(CO)4 was immobilised in permethylated β-CD (TRIMEB) by addition of the guest to a solution of TRIMEB in dichloromethane. Removal of the solvent led to the isolation of an inclusion compound with a 2∶1 host∶guest stoichiometry, as evidenced by powder X-ray diffraction, thermogravimetric analysis, FTIR and 13C CP MAS NMR spectroscopy. The electrochemical properties of (FcNN)Mo(CO)4 upon encapsulation are discussed.

INTRODUCTION: The measurement of platelet inhibition (PI) level may be useful in quantifying the risk of thromboembolic complication in subjects undergoing endovascular treatment using implantable materials. We studied the predictability of the VerifyNow point-of-care assay in a large sample of consecutive neurointerventional procedures. METHODS: The percentage of P2Y12-inhibition was systematically measured in a total of 271 procedures (245 patients). The incidence of poor response and adverse events within the first 48 hours were recorded. RESULTS: The overall occurrence of poor response after a single loading-dose of clopidogrel of 300 mg was 61.3 % using a cut-off of 40 % and 43.9 % using a cut-off of 20 %. In the analysis of the incidence of adverse events by P2Y12-inhibition grouping, a significant association was observed between thromboembolic events and low response, with an overall incidence of 10.2 % (cutoff of 40 %) and 11.8 % (cut-off of 20 %). The assessment of predictability using different cut-offs showed that more than 90 % of thromboembolic events would be in the group of poor responders using a 40 % cutoff and more than 75 % using 20 %. CONCLUSION: The use of the VerifyNow assay in the neurointerventional context seems a valuable tool in the early detection of individuals at risk of perioperative thromboembolic adverse events.

Ring Slippage vs Charge Transfer in the Reductive Chemistry of [IndMo(CO)₂(α-diimine)]⁺ Cations

Organometallics (2006)

Cláudia C. L. Pereira Paulo J. Costa Maria José Calhorda Cristina Freire Sandra Rodrigues

Thirteen complexes of the type [IndMo(CO)2L2]+ were prepared from IndMo(η3-C3H5)(CO)2 by protonation with HBF4·Et2O followed by addition of α-diimine ligands L, in the presence of 1,2-dimethoxyethane. The complexes are numbered as follows: L = 1,4-bis(p-tolyl)diazabutadiene (p-tolDAB, 1), 1,4-bis(cyclohexyl)diazabutadiene (cyDAB, 2), biquinoline (biq, 3), 5,6-Ph2-3-(2-py)-1,2,4-Tz (tz, 4), dipyrido[3,2-a:2',3'-c]phenazine (dppz, 5), 2,2'-bipyridine (bipy, 6), 4,4'-diphenyl-2,2'-bipyridine (4,4'-Ph2-bpy, 7), 1,10-phenanthroline (1,10-phen, 8), 4,7-diphenyl-1,10-phenanthroline (4,7-Ph2-1,10-phen, 9), 4,7-dimethyl-1,10-phenanthroline (4,7-Me2-1,10-phen, 10), 2-(2-pyridyl)benzimidazole (2-(2-py)-benz, 11), 2,2'-biimidazole (2,2'-Biim, 12), 1,2-phenylenediamine (phendiam, 13). The bonding mode of the ligand in 4 was ascertained by single-crystal X-ray diffraction. None of the complexes undergo NCMe addition to form ring-slipped [(η3-Ind)Mo(CO)2L2(NCMe)]+ species. The reductive electrochemistry was studied in order to search for possible reductively induced ring-slippage rearrangements. In the cases of 1−5 reversible reduction processes were observed. UV−vis spectroscopy combined with DFT calculations provided an interpretation for the structures of the reduced species. The data suggest that the unpaired electron in the formally 19e reduced products [IndMo(CO)2L2]• is localized on the α-diimine ligand with minimal structural changes and no indenyl slippage taking place. However, such slippage is predicted to take place with the second reduction step, but in most cases MoL2 bond breaking leads to irreversible electrochemistry.
