26. Very recently, Miura reported rhodium-catalyzed cross dimerization of silylacetylenes and internal alkynes: T. Katagiri, H. Tsurugi, A. Funayama, T. Satoh, and M. Miura, Chem. Lett. 2007, 36, 830. Although the present reaction in this manuscript is similar to that reported by Miura, we have studied mechanistic aspects of the reaction including characterization of the intermediates in the catalytic cycle as well as its synthetic aspects.

40. The addition of 1-octyne did not give the cross-dimerization product.
41. 2/dpph catalyst can also be applied to the addition to unsymmetrical arylacetylenes to give the corresponding enynes in high yields, although their regioselectivity was lower. For example, the addition of 2m to 1c gave a 92% yield of the hydroalkynylation products consisting of 3cm (53%) and 4cm (47%).
