Abstract

Dig this: 5-exo-dig carbocyclization of 1 into 2 features intramolecular carbopalladation of alkyne with Pd enolate (see scheme). DFT calculations show that the key Pd enolate forms by deprotonation assisted byb PdII acetate. Subsequent intramolecular alkyne carbopalladation, Z-E isomerization of the formed vinyl palladium species, and protiodepalladation leads to E-alkylidene indanones. (Chemical Equation Presented).
