2346-26-1, 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. 2346-26-1, name is Oxazolidine-2,4-dione. A new synthetic method of this compound is introduced below.
5.2. 3-{[1-(1-Isoquinolyl)-4-piperidyl]methyl}-1,3-oxazolidine-2,4-dione A solution of 2.01 g (9.95 mmol) of diisopropyl azodicarboxylate (DIAD) in 5 ml of tetrahydrofuran is added dropwise, under an inert atmosphere, to a solution of 2.4 g (9.95 mmol) of [1-(1-isoquinolyl)-4-piperidyl]methanol, prepared in step 5.1, 2.87 g (10.94 mmol) of triphenylphosphine and 1.21 g (11.93 mmol) of 1,3-oxazolidine-2,4-dione in 40 ml of tetrahydrofuran, cooled to about -10 C., the temperature of the reaction medium being maintained throughout between -10 C. and 0 C. Stirring is then continued at 0 C. for 1 hour and then at 25 C. for 18 hours. The mixture is concentrated under reduced pressure and the residue is taken up in dichloromethane and 10 ml of aqueous 5% sodium hydroxide solution. The aqueous phase is separated out and then extracted twice with dichloromethane. The organic phases are combined and washed successively with aqueous hydrochloric acid solution (1N) and then with saturated aqueous sodium hydrogen carbonate solution and with saturated aqueous sodium chloride solution. The organic phase is dried over sodium sulfate and the filtrate is concentrated under reduced pressure. The residue thus obtained is purified by chromatography on silica gel, eluding with a 99/1/0.1 and then 98/2/0.2 mixture of dichloromethane, methanol and 28% aqueous ammonia. 3.57 g of oxazolidinedione are thus obtained in the form of an orange paste., 2346-26-1
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 about2346-26-1
