Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. 31608-22-7, Name is 2-(4-Bromobutoxy)tetrahydro-2H-pyran, molecular formula is C9H17BrO2. In a Article，once mentioned of 31608-22-7, Synthetic Route of 31608-22-7
Methyl non-8-ynoate and methyl Z-non-5-en-8-ynoate have been converted to their hexacarbonyldicobalt complexes.These have been converted by reaction with ethylene to 5-oxo-1-cyclopentene-1-heptanoic acid and 7-(5-oxo-1-cyclopenten-1-yl)-5-heptenoic acid methyl esters, known intermediates in the synthesis of 1- and 2-series prostaglandins respectively.The first has also been treated with cyclopentene to yield 4,5,6,6a-tetrahydro<2-(6-methoxycarbonylhexyl)>-1(3aH)-pentalenone and then by addition of the cuprate reagent from E-1-iodo-3-(t-butyldimethylsilyloxy)-oct-1-ene and removal of the silyl group to (+/-)-11-deoxy-10alpha,11alpha-trimethyleneprostaglandin E1 methyl ester and its 15-epimer.The methyl Z-non-5-en-8-ynoate was obtained from Z-1-bromo-7-tetrahydropyranyloxyhept-2-ene by coupling with ethynylmagnesium bromide followed by acid hydrolysis, oxidation and esterification.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Synthetic Route of 31608-22-7. You can get involved in discussing the latest developments in this exciting area about 31608-22-7
