Aplicaciones

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.

Notas

Light sensitive. Store in a cool place. Incompatible withbases, strong oxidizing agents, copper, peroxides, silver, silver oxides, mercury and mercury oxides.
