STAR Protocols, Vol 4, Iss 1, Pp 102140- (2023)
Summary: In this protocol, we describe the application of a halogen(I) complex as a highly active non-metallic complex catalyst. Specifically, we present a detailed guide to synthesize the halogen(I) complex catalyst and utilize it as an anion-bindin

Summary: The three-center-four-electron halogen bond (3c4e X-bond) presents a fundamental design concept for catalysis. By integrating halogen(I) (X+: I+ or Br+), the bis-pyridyl ligand NN, and a non-nucleophilic counteranion Y, we developed non-meta

In multidomain proteins, individual domains connected by flexible linkers are dynamically rearranged upon ligand binding and sensing changes in environmental factors, such as pH and temperature. Here, we characterize dynamic domain rearrangements of

The Wittig reaction of perfluorohalobenzaldehydes was systematically studied to investigate perfluorohalostyrenes (TFXS) as functional monomers of halogen bond-driven smart polymer materials. The reaction proceeded efficiently in THF using 1,1,3,3-te

Linker structures were systematically investigated for use in designing halogen-bond donor catalysts with two-point activation modes based on perfluoroiodobenzenes. Tetrafluorophenylene, phenylene, and acetylene were examined as potential linkers, an
