of quaternary carbon-centered 1-indanones in moderate to good chemical yields. The reaction of enynones with Togni’s reagent and chloro- or bromotrimethylsilane afforded halo- and CF3-containing 1-indenones. However, the addition of K3PO4 as a base into the catalytic system led to forming cyano-anchored (Z)-1-indanones as major stereoisomeric products. This strategy exhibits remarkable compatibility
