摘要
Allene undergoes cyclodimerization to 1,3- and 1,2-dimethylenecyclobutane in the vapor phase over phosphine-modified nickel carbonyls. A polymeric complex of composition [p-(C6H5)2PC6H4P(C6H5)2.Ni(CO)2]x is a particularly effective catalyst. This same complex catalyzes the cyclomerization of allene in the liquid phase to a tetramer, a pentamer, and higher oligomers. © 1969, American Chemical Society. All rights reserved.
