Cycloisomerization is a totally atom economic procedure which converts dienes and enynes into cyclic molecules. Modification of Grubbs' 2nd generation catalysts by reaction with dimethylformamide provides a new species able to catalyse this transformation

Intramolecular [2+2+1] cycloaddition of diynes with carbon monoxide was catalyzed by Vaska's complex (IrCl(CO)(PPh3)2) or IrCl(cod)(dppp), and cyclopentadienones were obtained in good to high yields. The first catalytic synthesis of
