Pyridinium triflate catalyzed intramolecular alkyne-carbonyl metathesis reaction of O-propargylated 2-hydroxyarylaldehydes

3,5-Dibromopridinium trifluoromethanesulfonate catalyzes the intramolecular alkyne-carbonyl metathesis reaction of a variety of O-propargylated 2-hydroxyarylaldehydes and ketones bearing alkyl, aryl and heteroaryl substituted internal alkynes to provide v

Barluenga's reagent with HBF4 as an efficient catalyst for alkyne-carbonyl metathesis of unactivated alkynes

Barluenga's reagent (IPy2BF4, Py = pyridine) treated with HBF4 efficiently catalyzes the inter- and intramolecular alkyne-carbonyl metathesis of unactivated alkynes with aldehydes or ketones, most of which proceed at room temperature. This work represents the first catalytic application of the Barluenga's reagent.

Alkynes as synthetic equivalents to stabilized wittig reagents: Intra- and intermolecular carbonyl olefinations catalyzed by Ag(I), BF3, and HBF4

(Chemical Equation Presented) The first use of cationic silver (AgSbF 4) as a catalyst for intra- and intermolecular alkyne - carbonyl coupling to form conjugated enones is described, and a comparison to corresponding Bronsted acid (HBF4/
