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.80841-78-7. A new synthetic method of this compound is introduced below., 80841-78-7
Example 3; Trityl olmesartan medoxomil (III); A solution of potassium salt 4 in methyl ethyl ketone from the preceding experiment (ca. 20 g of the salt) was diluted with methyl ethyl ketone (290 ml), and, after adding potassium iodide (2 g) and 4-chloromethyl-5-methyl-l,3-dioxol-2-one (7 g), the mixture was stirred at 50 0C for 7.5 h. After the reaction was completed, the mixture was filtered, and the filtrate was washed with methyl ethyl ketone (3 x 50 ml). After concentrating to ca. 160 ml in vacuo, ethanol (250 ml) was added, and the reaction mixture was again concentrated to ca. 300 ml in vacuo.The concentrated product in ethanol was inoculated and stirred at 50 0C for 0.5 h, and after getting thicker, diluted with ethanol (50 ml) and cooled to 20 C. The precipitated product was sucked off, washed with ethanol (2 x 20 ml) and dried in a vacuum drier at 50 C. 14.4 g (86 %) of the product was obtained.
This molecular description is the mechanism of the reaction; it describes how individual atoms, ions, or molecules interact to form particular products. The stepwise changes are collectively called the reaction mechanism.
