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.
A solution of 1.50 g (6 mmol) of 4-bromobenzyl bromide and 0.73 g (7.2 mmol) of 1,3-oxazolidine-2,4-dione in 6 ml of tetrahydrofuran is admixed dropwise with a solution of 1.39 g (12 mmol) of 1,1,3,3-tetramethylguanidine in 6 ml of tetrahydrofuran. The mixture is stirred at ambient temperature overnight. 50 ml of ice-cold aqueous hydrochloric acid (1N) and 100 ml of ethyl acetate are added. The organic phase is separated after settling out and washed successively with 25 ml of water and 25 ml of saturated aqueous sodium chloride solution. It is dried over sodium sulphate and the filtrate is concentrated under reduced pressure. The residue is purified by chromatography on silica gel, eluting with an 80/20 mixture of cyclohexane and ethyl acetate. 1.14 g of product are obtained in the form of white crystals. m.p. ( C.): 88-90 C.
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
