1,3,5-Trienes are common byproducts in metal-mediated [2+2+2] cocyclizations between two alkynes and an alkene (see Section The competition between linear and cyclic alkyne/alkene 2:1 co-oligomerizations to give trienes or cyclohexa-1,3-dienes, respectively, is not as yet fully controllable but the formation of linear products may sometimes predominate.
