37830-90-3, The molecularity is the number of molecules that collide during that step in the mechanism. If only a single reactant molecule in an elementary reaction, that step is designated as unimolecular; if there are two reactant molecules, it is bimolecular.37830-90-3. A new synthetic method of this compound is introduced below.
PREPARATION 18 4-Carbo-(5-methyl-2-oxo-1,3-dioxol-4-ylmethoxy)methylpiperazine hydrochloric acid salt Combine 4,5-dimethyl-1,3-dioxol-2-one (3.42 g, 30 mmol), N-bromosuccinimide (5.34 g, 30 mmol) and AIBN (500 mg, 3 mmol) in anhydrous carbon tetrachloride (100 mL). Heat at reflux. After 2 hours, cool and filter. Concentrate the filtrate to give 4-bromomethyl-5-methyl-1,3-dioxol-2-one (6.5 g, crude) as an oil, which can be used for the next step without further purification.
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps.
