Diethyl 2-bromomalonate
WebA mixture of ethyl 2-bromo-propanedioic acid diethyl ester (32.0 g, 133.2 mmol) and thioacetamide (10.0 g, 133.2 mmol) in toluene (130 ml) is refluxed for 4 h and then … WebOct 1, 2024 · Initially, we investigated the reaction of diethyl 2-fluoromalonate 1a as its alkali metal salt with gaseous HFP in various aprotic solvents. Due to the -I -effect of the fluorine atom and thus increased acidity of the CH proton, 1a was easily deprotonated using NaH or n -BuLi in dry monoglyme (MG) to give the corresponding salt 2a ( Scheme 1 ).
