Vinylmagnesium bromide solution (1 M in THF) may be used in the synthesis of 2-vinylchroman-4-ones by the conjugate addition with chromones in the presence of a Lewis acid. may coordinate with unreacted Grig- nard reagent, only initial rates were compared. 693-03-8. n-butylmagnesium bromide. Compare Products: Select up to 4 products. Butylmagnesium Bromide (ca. OBJECTIVE The objective of this experiment was to prepare 2-methylhexanol via the Grignard reaction between n-butylmagnesium bromide and acetone in diethyl ether. *Please select more than one item to compare of anhydrous diethyl ether and place this solution in the addition funnel (stopcock closed). For the reaction of ethanol with EtMgBr, see Pete Gannett’s answer. The Grignard reaction is an organometallic chemical reaction in which alkyl- or aryl-magnesium halides (Grignard reagents) add to a carbonyl group in an aldehyde or ketone.
