Description and Uses
Propargyl bromide is a Shock sensitive liquid, lachrymator. Supplied as an 80% solution in toluene stabilized with magnesium oxide. Alternative formulations are currently under development.
Propargyl bromide, 80% in toluene is used to prepare betulonic acid-peptide conjugates with anti-inflammatory activity and propargylic amines employed in enyne metathesis. It finds application in the propargylation of spiro ketones, allylic alcohols and enone complexes. In Barbier-type reaction, it reacts with aldehydes to give alkyne alcohols. It is actively involved in the synthesis of polyethylene glycol (PEG) and peptide-grafted polyesters.
