The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1768-64-5, Name is 4-Chlorotetrahydropyran, molecular formula is C5H9ClO. In a Patent£¬once mentioned of 1768-64-5, Safety of 4-Chlorotetrahydropyran
Preparation of 1-(4-tetrahydropyranyl)- or 1-(4-tetrahydrothiopyranyl)prop-1-en-3-ones
A process for the preparation of 1-(4-tetrahydropyranyl)- or 1-(4-tetrahydrothiopyranyl)prop-1-en-3-ones of the general formula I STR1 where R1 is hydrogen, C1 – to C10 -alkyl, C1 – to C10 -alkoxy or aryloxy, R2 is hydrogen, C1 – to C4 -alkyl, or aryl which is unsubstituted or substituted by C1 – to C4 -alkyl and/or halogen, and X is oxygen or sulfur, by reacting 1-aminoprop-1-en-3-ones of the general formula II STR2 where R1 and R2 are as defined above, and R3 and R4, independently of one another, are hydrogen, C1 – to C4 -alkyl, aryl or together are a C2 – to C7 -alkylene chain, with a 4-tetrahydropyranyl- or 4-tetrahydrothiopyranylmagnesium halide of the general formula III STR3 where X is as defined above and Y is halogen, at from -20 to 100 C., and novel 1-(4-tetrahydropyranyl)- or 1-(4-tetrahydrothiopyranyl)prop-1-en-3-ones are described.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 1768-64-5 is helpful to your research., Safety of 4-Chlorotetrahydropyran
