New learning discoveries about 541-16-2

The chemical industry reduces the impact on the environment during synthesis Di-tert-Butyl malonate. I believe this compound will play a more active role in future production and life.

Application of 541-16-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 541-16-2, name is Di-tert-Butyl malonate, This compound has unique chemical properties. The synthetic route is as follows.

General procedure: To a cooled(0 C) solution of NaH (60% in mineral oil, 2.2 eq.) in DMF (1.0 M) was slowly added di-t-butylmalonate (1.1 eq.). After 15 min, 2-fluoronitrobenzene derivative (5.00 g) was added to the reactionmixture dropwise at 0 C. The resultant mixture was stirred at room temperature overnight and quenchedwith 0.1 N HCl aq. The resultant aqueous phase was extracted with EtOAc/n-hexane = 1/1. The combinedorganic phases were washed with brine. The resultant organic phase was dried over Na2SO4, filtered, andthe filtrate was concentrated in vacuo. The residue was purified by silica gel column chromatography(n-hexane/EtOAc = 100/0 – 30/70).

The chemical industry reduces the impact on the environment during synthesis Di-tert-Butyl malonate. I believe this compound will play a more active role in future production and life.
