The intramolecular cycloaddition reactions of the tetraene ethers 10 and 17 and the triene ether 28 were investigated. Acetone-sensitized excitation of 10 led to three intramolecular [2 + 2] cycloadducts 11-13. However, CuOTf-catalyzed photolysis of

Nickel complexes having a bulky tri(sec-alkyl)phosphine ligand catalyze hydroheteroarylation of alkynes at 35 degrees C. Selective activation of an Ar-H bond over an Ar-CN bond of N-protected 3-cyanoindoles is achieved by a proper choice of ligand an
