In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 39590-81-3 as follows., 39590-81-3
Step 3: Into a 2 L 3 necked round bottomed flask were placed a solution of cyclopropane-1,1- diyldimethanol (42 g, 410 mmol) in DCM (200 mL) and DMAP (126 g, 1.03 mol). The mixture was treated with a solution of TsC1 (173 g, 907 mmol) in DCM (500 mL) dropwise, while cooling to 0 C, over 30 mm. The resulting solution was allowed to stir for 2.5 h at roomtemperature. The reaction mixture was washed with H20, HC1 (iN) and brine, dried over Na2504 and concentrated under reduced pressure. This resulted in cyclopropane-1,1- diyldimethanediyl bis(4-methylbenzenesulfonate) as a solid
The chemical industry reduces the impact on the environment during synthesis 39590-81-3, I believe this compound will play a more active role in future production and life.
