Reaction of Grignard compounds with 4-chloro-2-methyl-3-butyn-2-ol in Diethyl Ether equivalents

Reactions of RMgX · THF complexes with 4-chloro-2-methyl-3-butyn-2-ol in aromatic hydrocarbons were studied. The complexes formed by arylmagnesium halides require the presence of anisole for the reaction to occur. 4-Chloro-2-methyl-3-butyn-2-ol can be synthesized by reaction of 2-methyl-3-butyn-2-ol with sodium hypochloride in the two-phase system water-benzene.

Unsaturated ester-amides of halogenated alkenes

This invention deals with new unsaturated ester-amides of α,β-unsaturated polycarboxylic acids derived from halogenated alcohols of the formula EQU1 wherein R is a divalent hydrocarbon moiety having at least one and no more than 10 carbon atoms, X is a member selected from the class of bromine and chlorine, and R' is a member selected from the class of hydrogen and a monovalent hydrocarbon containing at least one and no more than 20 carbon atoms. Typical ester-amides are the maleates, fumarates, itaconates and citraconates. These monomers possess fire-retardant properties and are useful for the synthesis of polymers and copolymers.
