55750-48-6, An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.55750-48-6, name is Methyl 2,5-dioxo-2,5-dihydro-1H-pyrrole-1-carboxylate. Here is a downstream synthesis route of the compound 55750-48-6
55750-48-6, Step 1: t-Butyl (2-(2-(2-aminoethoxy)ethoxy)ethyl)carbamate(250 mg, 1.0 mmol) andmethyl 2,5-dioxo-2,5-dihydro-1H-pyrrole-1-carboxylate (156 mg, 1.0 mmol) were combined in saturated aqueous NaHCO3 (10 ml) and stirred for 1.5 h at 0C. The reaction mixture was acidified to pH 2 with hydrochloric acid (2 M) and extracted with EtOAc. The organic phase was washed with brine, dried with MgSO4, and concentrated. The crude was purified by ISCO using 0-4% MeOH/DCM to give t-butyl (2- (2-(2-(2,5 -dioxo-2,5 -dihydro- 1 H-pyrrol- 1 -yl)ethoxy)ethoxy)ethyl)carbamate as a colorless oil. MS m/z 229.2(M+1-Boc). Retention time 0.963 mm. ?H NMR (400 MHz, Chloroform-d) 6 6.71 (s, 2H), 5.04 (bs,1H), 3.74 (t, J = 5.4 Hz, 2H), 3.64 (t, J = 5.4 Hz, 2H), 3.61-3.59 (m, 2H), 3.56-3.54 (m, 2H), 3.50 (t, J =5.2 Hz, 2H), 3.31-3.26(m, 2H), 1.44 (s, 9H).
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 55750-48-6
