7517-99-9, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular. 7517-99-9, name is 5-(Hydroxymethyl)oxazolidin-2-one. A new synthetic method of this compound is introduced below.
7517-99-9, General procedure: A Schlenk tube was charged with aryl bromide(1 mmol), oxazolidone(1.2 mmol), N,N-dimethylglycine(10.3mg, 0.1 mmol), recrystallized CuI(9.5mg, 0.05 mmol) and K2CO3(276mg, 2 mmol). The tube was evacuated and backfilled with argon(3 times) before dry DMF(0.5 ml) was added. The reaction mixture was stirred at 120 C until the corresponding aryl bromidewas completely consumed as monitored by TLC. The reaction mixture was extracted with ethyl acetate. The organic layer was washed with H2O and brine, and dried by Na2SO4. Removal of solvent in vacuo and purified by column chromatography on silica gel to provide the desired product.
In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about 7517-99-9 if you are interested.
