  substrate-directed regiochemistry of the cobalt-catalysed­ 1,4-hydrovinylation reaction is described. A variety of symmetrical and unsymmetrical 2,3-disubstituted 1,3-dienes are synthesised by ruthenium-catalysed enyne metathesis, and then reacted with a terminal alkene catalysed by cobalt(II) bromide-[1,2-bis(diphenylphosphino)ethane] [CoBr2(dppe)] under reductive conditions.

  with conjugated dienes yields two conjugated triene products depending on the regioselectivity of the C–C bond formation reaction via a ruthenacycle intermediate. The electronic and steric effects of alkynes are comprehensively evaluated based on Hammett's (σp) and Taft's (σ*, Es) substituent constants. An electron-withdrawing substituent favours the external position of the conjugated triene products
