24621-61-2, 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.24621-61-2, name is (S)-Butane-1,3-diol. A new synthetic method of this compound is introduced below.
e) (S)-4-Triisopropylsilanvloxv-butan-2-olTriethylamine (1.173 g) is added dropwise to a solution of 2.246 g triisopropylchlorosilaneand 1 g (S)-(+)-1,3-butanediol in 15 ml of dry tetrahydrofuran. The mixture is stirred for 48hours at room temperature, then is diluted with 400 ml of tert-butyl methyl ether and washedrespectively with 30 mM N HCI, 50 ml water and 50 ml of brine. The organic phase is dried(sodium sulphate), filtered and evaporated to dryness. The residue is purified by means offlash column chromatography (SiO2 60F) to provide the title compound as a colorless oil.Rf = 0.31 (EtOAc- heptane 1:5).
In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about 24621-61-2 if you are interested.
