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.

Type-II Red Phosphorus: Wavy Packing of Twisted Pentagonal Tubes [PDF]

open access: yesAngew. Chem. Int. Ed. e202307102 (2023), 2023
Elemental phosphorus exhibits fascinating structural varieties and versatile properties. The unique nature of phosphorus bonds can lead to the formation of extremely complex structures, and detailed structural information on some phosphorus polymorphs is yet to be investigated.

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 ...

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 ...

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.

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

Phosphorus-rich stars with unusual abundances are challenging theoretical predictions [PDF]

open access: yesNature Communications 11, Article number: 3759 (2020), 2020
Almost all chemical elements have been made by nucleosynthetic reactions in various kind of stars and have been accumulated along our cosmic history. Among those elements, the origin of phosphorus is of extreme interest because it is known to be essential for life such as we know on Earth.

Neutrophil Delivered Hollow Titania Covered Persistent Luminescent Nanosensitizer for Ultrosound Augmented Chemo/Immuno Glioblastoma Therapy

open access: yesAdvanced Science, 2021
Glioblastoma (GBM) is the most malignant brain tumor with unmet therapeutic demand. The blood‐brain‐barrier (BBB) and tumor heterogeneity limit the treatment effectiveness of various interventions.

First images of phosphorus molecules towards a proto-Solar analog [PDF]

open access: yes, 2022
The chemistry of phosphorus in star- and planet-forming regions is poorly understood, despite the central role of phosphorus in terrestrial biochemistry. We present ALMA Band 3 and 4 observations of PO and PN towards the Class I protostar B1-a, representing the first spatially resolved observations of phosphorus carriers towards a Solar-type star ...
