摘要：

Various terminal alkynes in the presence of 5 mol% of RhCl(PPh3)(3) were homo-coupled to the conjugated enynes. 1,6-Enynes in the presence of 5 mol% RhCl(PPh3)(3) and 10 mol% Ag(I) salts underwent [2+2+2]-cyclization among two triple bonds and one pendant double bond in good to excellent yields.
