Exploring the Reactivity of Perphenylheptasilanes: Synthesis of Terminally Functionalized Derivatives

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Different methods to prepare 1,7‐disubstituted tetradecaphenylheptasilanes are explored. The triflated heptasilane TfO‐(SiPh2)7‐OTf reacts with alkali metal halides to produce the 1,7‐dihalogenides X‐(SiPh2)7‐X (X = F, Cl, Br, I). The 1,7‐dihydrogen derivative H‐(SiPh2)7‐H is obtained with LiAlH4 or (i‐Bu)2AlH as reducing agents.

An environmentally benign multi-component reaction: Highly regioselective synthesis of functionalized 2-(diarylphosphoryl)-1,2-dihydro-pyridine derivatives

Green Synthesis and Catalysis, 2022
A novel protocol was developed for the construction of highly functionalized 2-(diarylphosphoryl)-1,2-dihydropyridine derivatives (DAPDHPs) from 3-formylchromones (1), heterocyclic ketene aminals (HKAs, 2), and phosphine oxides (R2P(O)H, 3) via a novel ...

The Reaction 7Li(pi+,pi-)7B and its Implications for 7B

, 1998
The reaction 7Li(pi+,pi-)7B has been measured at incident pion energies of 30-90 MeV. 7Li constitutes the lightest target nucleus, where the pionic charge exchange may proceed as a binary reaction to a discrete final state.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Assessing Moisture Content of Coolstored Blueberries During Water Loss Scenarios Using Hyperspectral Imaging

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
Water loss is a key factor affecting the postharvest quality and shelf life of blueberries, and storage conditions (humidity and time) play an important role in regulating water retention capacity of stored berries. This study aims to explore the variation of moisture content (MC) in blueberries under different storage humidity and storage time ...
