3,3-Bis(chloromethyl)oxetane (BCMO) is an intermediate in the synthesis of poly(bis(azidomethyl)oxetane (PolyBAMO), an energetic polymer that is being studied for use as a propellant binder for rocket fuel.[2]

It is classified as an extremely hazardous substance in the United States .[3] It can cause kidney damage, lacrimation, and somnolence if consumed.[1]

Preparation and reaction

BCMO is formed in solution via cyclization of pentaerythritol trichlorohydrin with a non-organic base like sodium hydroxide.[4]

BAMO can be formed from a reaction of BCMO with sodium azide. This reaction takes place in an alkaline solution with tetrabutyl ammonium bromide, which acts as a phrase transfer catalyst.[4]
