An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.31886-58-5, name is (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine. Here is a downstream synthesis route of the compound 31886-58-5, 31886-58-5
For a preparation of Ugi amine 7 refer to Marquarding, D. et al., J. Am. Chem. Soc. 1970, 92, 5389.In a 200 ml schlenk tube, Ugi amine 7 (4 g, 15 mmol) was dissolved in Et2O (50 ml) at room temperature, n-BuLi (12 ml, 30 mmol) was added to the mixture at that temperature and stirred overnight under an inert atmosphere. The reaction mixture was cooled to -78C and Iodine (9.52 g, 37.5 mmol) dissolved in THF (60 ml) was added over the course of 10 min. The reaction was stirred at -78C for 90 min before allowing to warm to room temperature, at which point it was allowed to stirred for an additional 90 min before quenching at 0C with sodium thiosulfate(aq)(50 ml, 25% w/v). Dilute with Et2O (30 ml), the layers were separated and the aqueous layer was further extracted with ether (50 ml x 3). The combined organic fractions were dried over MgSO4solvent remove in vacuo and purified via flash column chromatography (5% MeOH, 5% TEA in DCM) to yield product (3.18 g, 55%).1H NMR (400 MHz, CDCl3) delta 4.46 (dd, J = 2.4, 1.4 Hz, 1 H), 4.24 (t, J = 2.6 Hz, 1 H), 4.15 (dd, J = 2.7, 1.3 Hz, 1 H), 4.12 (s, 5H), 3.62 (q, J = 6.8 Hz, 1 H), 2.15 (s, 6H), 1.50 (d, J = 6.8 Hz, 3H).13C NMR (101 MHz, CDCl3) delta 90.21 (ipso Cp), 74.32 (Fc), 71.67 (Fc), 68.19 (Fc), 65.59 (Fc), 57.59 (CH*), 45.49 (ipso Cp), 41.22 (CH3), 16.01 (CH3).

Mp: melt at 58C-60C. aD(c = 0.0022 g/ml, DCM) = +7.3.
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about (R)-(+)-N,N-Dimethyl-1-ferrocenylethylamine, CAS: 31886-58-5
