One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 5631-96-9, Name is 2-(2-Chloroethoxy)tetrahydro-2H-pyran, molecular formula is C7H13ClO2. In a Article,once mentioned of 5631-96-9, Synthetic Route of 5631-96-9
Bismuth trichloride as mild reagent, has been found to be a worthful catalyst for tetrahydropyranylation of 1,2,3, allylic, benzylic alcohols, and symmetric di-ols. At room temperature the reagent THP(3,4-dihydro-2H-pyran) was successfully employed as pyranylating agent in presence of BiCl3catalyst without the use of a solvent and the yields of the products were found to be 90-96%. Further, the depyranylation of alcohols was achieved in quantitative yield by simple addition of MeOH using the same catalyst. The developed method was showed good chemo-selectivity in symmetrical diols for mono THP protection.
