(Chemical Equation Presented) Catalytic variant: Allyl silanes and silyl enol ethers 1 are good substrates for the catalytic highly enantioselective fluorodesilylation using a combination of a biscinchona alkaloid, N-fluorobenzenesulfonimide (NFSI), and base (see scheme). Pharmaceutically attractive 3-aryl-3-fluorooxindoles such as 3 can also be synthesized with high enantioselectivity.

A novel [18F]NF reagent and two novel radiochemical transformations have been developed: [18F]NFSi has been prepared from sodium dibenzenesulfonimide and reacted in the presence of silyl enol ethers and allylsilanes to deliver labell
