Efficient Concentration and Complete Destruction of Short‐Chain and Emerging PFAS in Contaminated Water via Integrated Interface Engineering‐Enhanced Carbon Felt Sorption and Photochemical Processes

Advanced Science, EarlyView.
A closed‐loop “Concentrate‐Destroy” strategy is presented for completely eliminating short‐chain and emerging PFAS, in which the new 3D PPy@P‐CF is used for efficiently concentrating PFAS and Cu2+‐mediated photodegradation is applied for the completely destroying PFAS in the sorbent regeneration eluent.

(Alkali metal)decarboxylation reaction: Lone pair participation and design of diastereoselective enolate formation

, 2022
Recently, we demonstrated that, contrary to the explanation in most textbooks on organic chemistry, the mechanism of the decarboxylation reaction can be more appropriately explained by the orbital theory, since the most electrondonating bond orbital, i.e.

Structure and mechanism of acetolactate decarboxylase [PDF]

, 2013
Acetolactate decarboxylase catalyzes the conversion of both enantiomers of acetolactate to the (R)-enantiomer of acetoin, via a mechanism that has been shown to involve a prior rearrangement of the non-natural (R)-enantiomer substrate to the natural (S ...

Decarboxylative Hydroalkylation of Alkynes [PDF]

Journal of the American Chemical Society, 2018
The merger of open- and closed-shell elementary organometallic steps has enabled the selective intermolecular addition of nucleophilic radicals to unactivated alkynes. A range of carboxylic acids can be subjected to a CO2 extrusion, nickel capture, migratory insertion sequence with terminal and internal alkynes to generate stereodefined functionalized ...
