Copper acetate mediated (4 + 2) annulation of sulfonylacetylenes with salicylic acids provides sulfonyl chromen-4-ones in the presence of benzotriazol-1-yloxy tri(dimethylamino)phosphonium hexafluorophosphate (BOP, Castro’s reagent) and 4-dimethylaminopyridine (DMAP) in MeNO2 at reflux for 3 h. The uses of various metal complexes and activating reagents are investigated for facile and efficient transformation

High-purity copper films were deposited at substrate temperatures between 150 and 225 o C via pyrolytic decomposition of a series of alkyne stabilized copper(I) hexafluoroacetylacetonate complexes. The copper-alkyne complexes display varying chemical and physical properties which are dependent upon the identity of the alkyne species used to stabilize the reactive copper(I) moiety. The relationship
