Allyl chloride

Allyl chloride is a colorless liquid with the chemical formula CH₂=CHCH₂Cl. It features an alkene group next to, or "allylic to", an alkyl halide group, It is insoluble in water but soluble in common organic solvents. It is a common as an alkylating agent relevant to the manufacture of pharmaceuticals and pesticides. It is also a component in thermosetting resins.

Allyl chloride is a common building block in organic synthesis. Illustrative important reactions include cyanation to allyl cyanide (CH₂=CHCH₂CN), reductive coupling to give diallyl,CH₂=CHCH₂CH₂CH=CH₂), complexation to palladium to give allyl palladium dimer, (C₃H₅)₂Pd₂Cl₂, and dehydrohalogenation to cyclopropene.

Allyl chloride is prepared by the reaction of propylene with chlorine gas at 500 °C.

Safety

Allyl chloride is toxic and flammable.
