DIETHYL DIBROMOMALONATE Chemical Properties,Uses,Production
Uses
Diethyl dibromomalonate is used for selective bromination of polyunsaturated ester enolates; converts alkenes into cyclopropanes in the presence of suitable heavy metal reagents.
Preparation
Diethyl dibromomalonate is prepared in 95% yield by reaction of diethyl malonate with bromine.
General Description
Diethyl dibromomalonate reacts with sodium methoxide in cyclohexene to afford dibromonorcarane. It also reacts with allyl(pyridine)cobaloximes to afford the corresponding allyl-substituted esters.
storage
lachrymator; light sensitive. Store in the dark under nitrogen. This toxic reagent should be handled in a fume hood.
