Preparation and characterization of carbene complexes of iron from azolyl and thienyl precursors

Preparation and characterization of carbene complexes of iron from azolyl and thienyl precursors. Raubenheimer, Helgard G.; Desmet, Mieke; Olivier, Pierre; Kruger, Gert J. (Department Chemistry Biochemistry, Rand Afrikaans University, Auckland Park 2006, S. Afr.). Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry, (23), 4431-4438 (English) 1996 Royal Society of Chemistry. CODEN: JCDTBI. ISSN: 0300-9246. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 Azolyl and thienyl Fe(II) complexes were synthesized by the addn. of 1-phenylpyrazol-5-yllithium, 5-(4,5-dihydro-4,4-dimethyloxazolin-2-yl)-2-thienyllithium, 2-(4,5-dihydro-4,4-dimethyloxazolin-2-yl)-3-thienyllithium or 5-(2-pyridyl)-2-thienyllithium to [Fe(Cp)(CO)2Cl] (Cp = h-C5H5). Protonation or alkylation of these precursor complexes yielded the corresponding amino(organo)-, organo(thio)- or heterometallacyclic alkoxy(amino)- and hydroxy(amino)carbene complexes as well as compds. in which the ligand shows more pyridinium character. The mol. structures of the pyrazolyl complex [Fe(Cp)(CO)2(C:CHCH:NNPh)] I and the pyrazolinylidene complex [Fe(Cp)(CO)2(CCH:CHNHNPh)][CF3SO3] II have Fe-C bond lengths of 1.98(2) and 1. 1126-00-7 is just another one chemical used in this study.969(5) ? resp. .

Effect of solvent and complexant on the regioselectivity of metalation

Effect of solvent and complexant on the regioselectivity of metalation. 2-(2-Furyl)pyridine. Ribereau, P.; Queguiner, G. (Lab. Chim. Org. Heterocycl., Inst. Natl. Super. Chim. Ind. Rouen, Mont-Saint-Aignan 76130, Fr.). Tetrahedron, 39(21), 3593-602 (French) 1983. CODEN: TETRAB. ISSN: 0040-4020. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 27 Lithiation of 2-(2-furyl)pyridine with BuLi is dependent on the nature of the solvent, Li complexant, and temp. w-Lithiation of the furan ring increases with the importance of the solvation of the Li atom (tetramethylethylenediamine > THF > ether > hexane). The a substituted deriv., which is the thermodynamically controlled product, is obtained in ether with a good yield either with diazabicyclooctane-BuLi or by hexamedthylphorphorotriamide-catalyzed migration of Li from w to a positions. 3319-99-1 and 680-31-9 are just another two chemicals used in this study. Furthermore, the relative reactivity of 2-(2-furyl)- and 2-(2-thienyl)pyridines indicates the predominant effects of O, N, and S atoms. .
