An inexpensive industrial refrigerant, HFO‐1234ze, is transformed into a versatile fluoroalkyl building block via a scalable, solvent‐free protocol. Utilizing the metal‐free photocatalyst 4CzIPN, efficient visible‐light‐induced radical addition to alkynes reveals distinct, substrate‐dependent stereoselectivities.

Fluorinated building blocks [PDF]
Julian A Cooper This work describes the functionalisation of carbon-hydrogen bonds in saturated hydrocarbons via free radical addition to fluorinated alkenes. For example, hexafluoropropene can be added to produce a mono-adduct:- A range of fluoroalkenes

Silica Coating Enhances the PFAS Photocatalytic Properties of Boron Nitride
A coating of 6 wt% SiO2 effectively covered the edges of BN, which lowered BN hydrolysis and increased PFOA photodegradation. ABSTRACT Boron nitride (BN) has recently emerged as a promising material capable of breaking down toxic perfluorooctanoic acid (PFOA) and other per‐ and polyfluoroalkyl substances (PFAS) through photocatalysis. However, chemical

A zinc‐mediated catalyst‐free cross‐electrophile couplingbetween gem‐difluoroenol sulfonates and N‐(acyloxy) phthalimides accesses structurally diverse α,α‐difluoroketones. It exhibits broad radical compatibility, reliable gram‐scale performance, and enables construction of elaborate fluorinated amino acid and glycosyl derivatives.

Restoration ecology in conflict along the Colorado front range
Abstract Introduction Cheatgrass (Bromus tectorum) is a challenge to restoration in western North America. It attracts the attention of academic and government research scientists, weed managers, and chemical companies. Attempts to control it cause conflicts among these groups.
