Mechanical Bond Enhanced Lithium Halide Ion-Pair Binding by Halogen Bonding Heteroditopic Rotaxanes [PDF]

, 2022
A family of novel halogen bonding (XB) and hydrogen bonding (HB) heteroditopic [2]rotaxane host systems constructed by active metal template (AMT) methodology, were studied for their ability to cooperatively recognise lithium halide (LiX) ion-pairs.

Design and Synthesis of a Chiral Halogen-Bond Donor with a Sp³-Hybridized Carbon–Iodine Moiety in a Chiral Fluorobissulfonyl Scaffold

Molecules, 2020
The first example of a chiral halogen-bond donor with a sp3-hybridized carbon–iodine moiety in a fluorobissulfonyl scaffold is described. The binaphthyl backbone was designed as a chiral source and the chiral halogen-bond donor (R)-1 was synthesized from

Halogen-Bond-Promoted Double Radical Isocyanide Insertion under Visible-Light Irradiation: Synthesis of 2‑Fluoroalkylated Quinoxalines

, 2016
A halogen-bond-promoted double radical isocyanide insertion with perfluoroalkyl iodides is reported. With perfluoroalkyl iodides as halogen-bond donors and organic bases as halogen-bond acceptors, fluoroalkyl radicals can be generated by a visible-light ...

Hybrid Molecular Dynamics for Elucidating Cooperativity Between Halogen Bond and Water Molecules During the Interaction of p53-Y220C and the PhiKan5196 Complex

Frontiers in Chemistry, 2020
The cooperativity between hydrogen and halogen bonds plays an important role in rational drug design. However, mimicking the dynamic cooperation between these bonds is a challenging issue, which has impeded the development of the halogen bond force field.

Complementary, Cooperative Ditopic Halogen Bonding and Electron Donor-Acceptor π-π Complexation in the Formation of Cocrystals

Molecules, 2022
This study expands and combines concepts from two of our earlier studies. One study reported the complementary halogen bonding and π-π charge transfer complexation observed between isomeric electron rich 4-N,N-dimethylaminophenylethynylpyridines and the ...

Halogen-Bond-Induced Consecutive C_sp³–H Aminations via Hydrogen Atom Transfer Relay Strategy

, 2020
The utilization of a halogen bond in a number of chemical fields is well-known. Surprisingly, the incorporation of this useful noncovalent interaction in chemical reaction engineering is rare. We disclose here an uncommon use of halogen bonding to induce

Comparison of Shear Bond Strengths of Orthodontic Brackets Bonded with Three Different Curing Techniques

Turkish Journal of Orthodontics, 2005
The aim of our study was to compare shear bond strengths of orthodontic brackets bonded with chemically cured, halogen light cured and LED cured adhesive systems. 45 extracted human premolar teeth were randomly divided into 3 groups.
