PREPARATION OF MONOFLUOROCARBOXYLIC ACIDS USING N,N-DIETHYL-1,1,2,3,3,3-HEXAFLUOROPROPYLAMINE

A method is outlined for the preparation of monofluorocarboxylic acids using Ishikawa's reagent, (C2H5)2NCF2CHFCF3 (PPDA), directly from hydroxyesters, or indirectly from monofluorinated alkylbenzenes, followed by the oxidation of the phenyl ring to a carboxylic acid.The chiral fluorocarboxylic acids, (2S) and (2R)-3-fluoro-2-methylpropionates (>99percent ee) and (2S)-2-fluoropropionic acid (55percent ee) are prepared as are 3-fluoropropionate and 4-fluorobutyrate.

Stabilization and Extraction of Fluoride Anion Using a Tetralactam Receptor

A neutral tetralactam macrocycle was prepared in a few minutes in one pot and at high concentration using commercially available starting materials. NMR titration studies in DMSO revealed an anion affinity order of F- > AcO- > Cl- > Br-. The receptor affinity for F- is very high due in part to formation of a self-complementary dimer comprised of two "saddle shaped" complexes. An X-ray crystal structure showed that the two F- ions within the dimer are separated by 3.39 ?. The electrostatic penalty for this close proximity is compensated by attractive interactions provided by the surrounding tetralactam molecules. Reactivity experiments showed that stabilization of F- as a supramolecular complex abrogated its capacity to induce elimination and substitution chemistry. This finding raises the idea of using tetralactam macrocycles to stabilize fluoride-containing liquid electrolytes within redox devices such as room-temperature fluoride-ion batteries. A lipophilic version of the tetralactam macrocycle was prepared and used to extract F- from water into a chloroform layer with high efficiency. The favorable extraction is due to the architecture of the extracted dimeric complex, with all the polarity located within the core of the self-associated dimer and all the nonpolar functionality on the exterior surface.

Efficient protocol for the SO2F2-mediated deoxyfluorination of aliphatic alcohols

Alkyl fluorides are prevalent in both the pharmaceutical and agrochemical industries. As such, there has been significant interest over the past 40 years in the development of new synthetic methods to access these important fluorinated motifs. Herein we report the sulfuryl fluoride-mediated deoxyfluorination of alcohols using room temperature reaction conditions in only an hour. A wide range of primary aliphatic alcohols were efficiently converted to the corresponding fluoride in 46-70% isolated yields. Secondary alcohols were also effectively deoxyfluorinated in 50–92% yields. Chiral secondary alcohols were cleanly converted to the corresponding alkyl fluoride with only a minor deterioration of the enantioenrichment. A steroid derivative also underwent deoxyfluorination in 50% yield and 5.9:1 dr, with the major product resulting from net inversion of the stereocenter.

A Series of Deoxyfluorination Reagents Featuring OCF2Functional Groups

Research on perfluoroalkyl ether carboxylic acids (PFECAs) as alternatives for perfluoroalkyl substances continues with the goal of protecting the environment. However, very little is known about the utilization of decomposition products of PFECAs. We report herein a new series of deoxyfluorination reagents featuring OCF2 functional groups derived from certain PFECAs. Alkyl fluorides were generated from various alcohols in ≤97% yield by these novel reagents. The mechanistic experiment verified in situ generation of carbonic difluoride (COF2).

Open-Shell Fluorination of Alkyl Bromides: Unexpected Selectivity in a Silyl Radical-Mediated Chain Process

We disclose a novel radical strategy for the fluorination of alkyl bromides via the merger of silyl radical-mediated halogen-atom abstraction and benzophenone photosensitization. Selectivity for halogen-atom abstraction from alkyl bromides is observed in the presence of an electrophilic fluorinating reagent containing a weak N-F bond despite the predicted favorability for Si-F bond formation. To probe this surprising selectivity, preliminary mechanistic and computational studies were conducted, revealing that a radical chain mechanism is operative in which kinetic selectivity for Si-Br abstraction dominates due to a combination of polar effects and halogen-atom polarizability in the transition state. This transition-metal-free fluorination protocol tolerates a broad range of functional groups, including alcohols, ketones, and aldehydes, which demonstrates the complementary nature of this strategy to existing fluorination technologies. This system has been extended to the generation of gem-difluorinated motifs which are commonly found in medicinal agents and agrochemicals.
