497-25-6, 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. 497-25-6, name is Oxazolidin-2-one. A new synthetic method of this compound is introduced below.
General procedure: In a 250 cm3 two-neck round-bottom flask equipped with astir-bar, CuCl2(0.2 equiv.), nitrogen nucleophile (5 equiv.),and Na2CO3(2 equiv.) were combined. The reaction flask was purged with oxygen gas. A solution of pyridine(2 equiv.) in dry toluene (0.06 M) was added to the reactionflask and stirred at 70 C. After 0.5 h, a solution ofthe respective alkyne (1.0 equiv.) in dry toluene (0.033 M)was added to the flask over 4 h using a syringe pump. Afteraddition of alkyne/toluene solution, the reaction mixture wasallowed to stir at 70 C overnight. After cooling to r.t., thecrude mixture was concentrated under reduced pressure. Theresidue was purified by column chromatography on silicagel.
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 497-25-6 if you are interested.
