chiral fluorine‐containing molecules is important for several scientific disciplines. We herein disclose a straightforward method for the preparation of chiral organofluorine molecules that is based on the iridium‐catalyzed asymmetric hydrogenation of trisubstituted alkenyl fluorides. This catalytic asymmetric process enables the synthesis of chiral fluorine molecules with or without carbonyl substitution

When oxygen reacts with CO on Ag surface, the silver surface is fully coveed by oxygen, but only a limited part of the chemisorbed oxygen participates in the reaction. Such characteristic behavior was discussed on the basis of STM observation.

Fluorination of allyl beta-keto carboxylates using N-fluoro-2,4,6-pyridinium triflate gave allyl a-fluoro-a-keto carboxylates. Reaction of allyl alpha-fluoro-beta-keto carboxylates with formic acid in the presence of palladium-phosphine catalyst gave alpha-fluoro ketones. When the palladium-catalyzed reaction was carried out without formic acid, the decarboxylation-allylation took place to give alpha-fluoro-allylketones. Decarboxylation-dehydrogenation to afford alpha-fluoro-alpha,beta-unsaturated ketones was carried out with palladium catalysts in acetonitrile.
