Industrial hydration of alkenes conditions
Web14 jul. 2014 · It has been found in the literature that alkynes with methanol as a solvent can be hydrated to the expected ketones via vinyl ether intermediates.11,12 However, for the hydration catalyzed by the gold isocyanide complexes (Cat-1 and Cat-2), no signal of vinyl ether intermediates was detected by GC-MS analysis. WebA set of convenient conditions for the title reaction is used to determine directly relative reactivities of alkenes with widely-varying steric requirements. Previous determinations did not use one set of conditions for all alkenes, but developed parameters in order to compare alkene reaction rates run in different solvents and in different concentrations; …
