Synthesis of formylcyclopentadienyltricarbonylrhenium and some of its properties

Synthesis, characterization and anti-Trypanosoma cruzi evaluation of ferrocenyl and cyrhetrenyl imines derived from 5-nitrofurane

“…The solvents such as CH 2 Cl 2 , C 6 H 6 , MeOH and THF were obtained commercially and were purified using standard methods. Complexes (h 5 -C 5 H 4 CHO)Re(CO) 3 [19], (h 5 -C 5 H 4 NH 2 )Re(CO) 3 [20], (h 5 -C 5 H 4 CN)Re(CO) 3 [21], (h 5 -C 5 H 4 CH 2 NH 2 )Fc [22], (h 5 -C 5 H 4 NH 2 ) Fc [23] (Fc ¼ Fe(h 5 -C 5 H 5 )) were prepared according to a procedure in the literature. The infrared spectra were recorded in solution (NaCl cell) or as solid (KBr pellets) on a PerkineElmer FT-1605 spectrophotometer.…”

“…The unreported 5a was obtained by the reduction of cyanocyrhetrene [21] with LiAlH 4 . This compound is quite unstable and should be prepared immediately prior to use.…”

“…The cyanocyrhetrene [21] (170.0 mg, 0.50 mmol) was dissolved in dry THF (20.0 mL) at 0 C, and an excess of LiAlH 4 (2.0 mL, 1 M in THF, 2.0 mmol) was added dropwise. The mixture was then stirred for 1 h in a nitrogen atmosphere.…”

Synthesis, characterization, crystal structures and computational studies on novel cyrhetrenyl hydrazones

“…1, is the sole example [17]. Moreover, unsubstituted [Re{(η 5 -C 5 H 4 )-C(R 1 )=NNH 2 }(CO) 3 ] compounds still remain unknown.…”

Preparation and characterization of poly(amidoamine) dendrimers functionalized with a rhenium carbonyl complex and PEG as new IR probes for carbonyl metallo immunoassay

“…doi:10.1016/j.jorganchem.2004.09.035 described the preparation of the 4th generation poly(amidoamine) (PAMAM-G4) dendrimer tethered with 45 CpFe(CO) 2 -succinimidato (Fp) units and four biotin entities [18]. More recently, we have reported the conjugation of such PAMAM-G4 bearing [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Fp units with secondary antibodies, following a sitedirected multi-labeling procedure involving their glycosylated residues [19]. It is noteworthy that the use of dendrimers to achieve an amplification of the signal level in non-isotopic immunoassays is a relatively new concept [20,21].…”
