1273-86-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Ferrocenemethanol, cas is 1273-86-5,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a mixture of 1.0 mmol of ferrocenylcarbinol and 1.0 mmol of the corresponding heterocycle in 1.0 ml of methylene dichloride, 0.18 ml of 45 % aqueous solution of fluoroboric acid was added under vigorous stirring. The agitation was continued for 5 min then Et2O (15 ml), the same amount of cold water, and 5-10 mg of ascorbic acid were added to the reaction flask. After vigorous shaking of the mixture the organic solution was separated, washed with cold water (3×15 ml), the solvent was removed and the residue was dried over CaCl2. All types of products (pyrrolidine as well as imidazolidine and thiazolidine derivatives) were equally purified, namely by column chromatography (silica, eluent hexane EtOAc 3:1), and solids obtained after chromatography were crystalized from ethanol.1-(1-Ferrocenylmethyl)pyrrolidine-2-thione (5). (85%); orange powder; mp 104.8 – 105.6o. 1H NMR (400 MHz, CDCl3) delta (ppm): 2.02 (m, 2, 2), 2.61 (m, 2, 2), 3.90 (m, 2, 2), 4.12 (s, 2H, Fc), 4.14 (s, 2, 2), 4.13 (s, 5H, Fc), 4.25 (s, 2H, Fc). 13C NMR (100 MHz, CDCl3) delta (ppm): 19.8 (CH2), 45.2 (CH2), 49.3 (CH2), 52.1 (CH), 66.0 (C5H4), 67.6 (C5H4), 68.8 (C5H4), 68.9 (C5H4), 69.1 (C5H5), 86.9 (ipso-C5H4), 200.1 (C=S) Calc. for C15H17FeNS: 61.22; H, 5.74; N, 4.69; Fe, 18.67; S, 10.72. Found: C, 60.21; H, 5.73; Fe, 18.66; N, 4.68; S, 10.72. EI/MS, m/z (RI%): 299 [M]+ (46).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Ferrocenemethanol, 1273-86-5
