The existence of a peroxygen acid of sulfur was recognized nearly one and half centuries
ago, 1, 2 but it was not until 1898 that Caro 3 demonstrated the existence of two such acids …

Bromination of organic substances is still an important reaction in modern synthetic
chemistry. In view of the increasing demand for sustainable synthetic chemistry, oxidative …

Palladium-catalyzed ligand directed C–H activation/halogenation reactions have been
extensively explored. Both the nature of the directing group and the substitution pattern on …

We developed performant in situ hypohalite, especially hypobromite, catalysis for the
oxidative dearomatization of low-reactivity electron-deficient arenols. The reaction scope …

An environmentally friendly and efficient protocol (KX/oxone) for oxidative halocyclization of
tryptamine/tryptophol derivatives was developed and demonstrated with 28 examples and …

A visible light-induced monochlorination of cyclohexane with sodium chloride (5: 1) has
been successfully accomplished to afford chlorocyclohexane in excellent yield by using …

The nucleophilicity of the substituents in iodobenzene pre-catalysts have a huge impact on
product selectivity in iodine (III) triggered halogenations, steering the reactivity from solely …

Reported here is the development of an environmentally friendly catalytic (KBr/oxone) and
solvent-free protocol for the Achmatowicz rearrangement (AchR). Different from all previous …

A mild and versatile procedure for the bromination of olefins and activated arenes by in situ
generation of 'Br+'using (diacetoxyiodo) benzene and lithium bromide is presented. The …

This paper describes a mild phenyliodine diacetate mediated method for selective
chlorination, bromination, and iodination of indole C–H bonds using sodium halide as a …
