It was shown that metathesis of enynes containing an internal triple bond sometimes proceeds in a nonselective manner, leading to the formation of three products: a normal diene A, a by-product B bearing an exocyclic double bond, and a bicyclic product C, containing a cyclopropane unit, Chemical Equation Presented) See: a V. Sashuk, K. Grela, J. Mol. Catal. A 2006, 257, 59;

It is reasonable to assume that the unwanted ROM/CM of a highly strained cyclobutene product 7, similar to that one shown in Scheme 3, could significantly be increased when the reaction is carried out under an ethylene atmosphere.

It should be noted that metathetical cycloisomerization of 1,n-enynes represents only a small branch of the vast tree of transition-metal catalyzed bond reorganization reactions of enynes. For selected key references, see: a C. Aubert, O. Buisine, M. Malacria, Chem. Rev. 2002, 102, 813;
