A convenient method for the [2+2+2] cyclotrimerisation of alkynes using Ti(OiPr)4/nBuLi is presented. Homotrimerisation of arylacetylenes proceeds within minutes with excellent regioselectivity. Moreover, the intermolecular construction of ABB heterotrimers can be achieved selectively from two different alkynes with similar electronic properties. The method is also suitable for the synthesis of pyridines.

The cobalt hydride reagent prepared in situ in THF at -20 deg C using CoCl2/NaBH4/Ph3P in the 1:1:4 ratio hydrodimerizes terminal alkynes into the corresponding trans, trans-1,3-dienes in good yields (65 to 86percent).
