preparation of novel carbon-11 PET imaging agents. The 17-trimethylsilyl enol ethers of 3-benzyloxy and 3-trifloxyestrone were prepared as substrates to react with methyl hypofluorite. Conditions for the reaction of methyl hypofluorite with simple substrates were optimized to provide reasonable reaction yields with the steroidal substrates. Following introduction of the methoxy substituent at the 16-position
