95715-86-9, 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. 95715-86-9, name is Methyl (R)-N-Boc-2,2-dimethyloxazolidine-4-carboxylate. A new synthetic method of this compound is introduced below.
4-Hvdroxymethyl-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (35b). A 250-ml two-necked flask was equipped with a magnetic stirring bar, reflux condenser bearing a drying tube and a dropping funnel. The flask was charged with tetrahydrofuran (100 ml) and lithium aluminium hydride (2.16 g, 57.0 mmol). While the suspension in the flask was stirred, a solution of the ester 12a (9.90 g, 38.2 mmol) in THF (50 ml) was added dropwise during 20 min. The reaction was monitored by thin layer chromatography. When the reaction was finished, the mixture was cooled in an ice bath and a solution of 10% potassium hydroxide (20 ml) was added dropwise during 10 min. The mixture was stirred for 2 h at room temperature, whereafter the white precipitate was removed by filtration through celite. The combined organic filtrates were washed with 100 ml of aqueous phosphate buffer (pH 7), and the aqueous layer was extracted with ether. The combined organic phases were dried and concentrated which gave the title compound (8.3 g, 94%). The residue was used without further purification.
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 about95715-86-9
