As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO267,mainly used in chemical industry, its synthesis route is as follows.,12582-61-5
To a CH2Cl2 solution (15 mL) of [(TPP)Fe]2(mu-O) (0.033 g, 0.024 mmol) was added trichloroacetic acid (0.010 g, 0.06 mmol). The mixture was stirred for 45 min, during which time the color of the solution changed from green to brown. The solvent was reduced to ?3 mL and hexane (10 mL) was added. The solution was slowly concentrated under reduced pressure until precipitation of the product occurred. The dark brown precipitate was collected by filtration, washed with hexane (2 ¡Á 15 mL), and dried in vacuo to give (TPP)Fe(OC(=O)CCl3) (0.020 g, 0.024 mmol, 50% isolated yield). Slow evaporation of a CH2Cl2/cyclohexane (1:1 ratio; 4 mL) solution of the product at room temperature gave suitable crystals for X-ray diffraction studies. IR (CH2Cl2, cm-1): upsilonOCO(asym) = 1704. IR (KBr, cm-1): upsilonOCO(asym) = 1709. UV-vis (lambda (relative epsilon, mM-1cm-1), 2 ¡Á 10-5 M in CH2Cl2): 411 (138), 509 (14), 571 (8), 681 (4) nm.
With the synthetic route has been constantly updated, we look forward to future research findings about Meso-5,10,15,20-Tetraphenyl-21H,23H-porphineironu-oxodimer,belong iron-catalyst compound
