THE observations recorded by Evans et al.1 establish that boron trifluoride alone cannot cause the polymerization of iso-butene or of di-iso-butene unless some unidentified promoter is present. It is the intention of this letter to direct attention to a number of similar observations affecting olefin reactions.
