solvent-free, nickel-catalyzed cycloaddition of alkynes to synthesize substituted cyclooctatetraene derivatives has been developed. this mechanochemical approach takes advantage of the frictional energy created by reusable nickel pellets, which also act as the catalyst. In contrast to solution chemistry, the major products are cyclooctatetraene isomers rather than ball mill liner; apron feeder pans; other cast wear parts. because of the brittle nature of this alloy, tramp iron will cause catastrophic failure of the blow bars. this material is used in secondary, tertiary and asphalt recycle applications where there is no tramp iron. cast white chromium iron is widely used in classic horizontal
