Diverse reactivity of the gem-difluorovinyl iodonium salt for direct incorporation of the difluoroethylene group into N- and O-nucleophiles

open access: yesCommunications Chemistry, 2022
The gem-difluoroethylene moiety is considered as a valuable building block in organic synthesis, but methods to introduce it into small molecules are generally limited to specific substrates.

Enabling liquid crystal elastomers with tunable actuation temperature

open access: yesNature Communications, 2023
Liquid crystalline elastomers are regarded as a kind of desirable soft actuator material for soft robotics and other high-tech areas. The isotropization temperature (Ti) plays an important role as it determines the actuation temperature and other ...

Rhodium hydride enabled enantioselective intermolecular C–H silylation to access acyclic stereogenic Si–H

open access: yesNature Communications, 2022
Construction of chiral organosilicon compounds could have implications in photophysical, biological, and chemical fields, as silicon is isoelectronic with carbon, and can mimic carbon atoms while providing slightly different properties.

Dietary phosphorus, serum phosphorus, and cardiovascular disease [PDF]

open access: yesAnnals of the New York Academy of Sciences, 2013
Recent epidemiologic studies have linked higher serum phosphorus concentrations to cardiovascular disease (CVD) events and mortality. This association has been identified in the general population and in those with chronic kidney disease (CKD). The risk of adverse outcomes appears to begin with phosphorus concentrations within the upper limit of the ...

Direct electrophilic and radical isoperfluoropropylation with i-C3F7-Iodine(III) reagent (PFPI reagent)

open access: yesCommunications Chemistry, 2023
The isoperfluoropropyl group (i-C3F7) is an emerging motif in pharmaceuticals, agrichemicals and functional materials. However, isoperfluoropropylated compounds remain largely underexplored, presumably due to the lack of efficient access to these ...

Natural Product-Oriented Photo-Induced Denitrogenative Annulations of 1-Alkenylbenzotriazoles

open access: yesMolecules, 2023
The photo-induced denitrogenative annulations of a variety of 1-alkenylbenzotriazoles were investigated. By judiciously manipulating the structural variations of 1-alkenylbenzotriazoles, two characteristic polycyclic skeletons associated with monoterpene
