Solid-State Organic Reactions Proceeding by Pulverization of Inorganic Solid-Supports. Reactions of lodosobenzene with Unsaturated Hydrocarbons on Acid-Treated Silica Gel
Pulverization of solid mixtures of hydrogen halide-treated silica gels, iodosobenzene, and alkenes or an alkyne in the absence of a solvent brings about smooth and rapid reaction to give halogenated or oxidized products in good yields.

The non-aqueous solution of chlorous acid is a versatile chlorinating agent for aromaticcompounds, e.g. alkylbenzenes, anisoles, and acetanililides. It is also an effective chlorine-substitute for the conversion of aryl bromides into aryl chlorides under mild conditions. The stoichiometry of the chlorination reaction is ArH+3HOClO→ArCl+2ClO2+2H2O, and the mode of dissociation of chlorous acid in
亚氯酸的非水溶液是用于芳族化合物( 例如 烷基苯,茴香醚和乙腈)的通用氯化剂 。它也是在温和条件下将芳基溴化物转化为芳基氯化物的有效氯代用品。氯化反应的化学计量是ARH + 3HOClO→ArCl等+ 2ClO 2 + 2H 2 O,和在二氯甲烷中的亚氯酸离解的模式被3HOClO→次氯酸+ 2ClO 2 + H 2 O.

SnCl4/Pb(OAc)4 acts as a safe source of Cl2 for the chlorination of aromaticcompounds. A variety of aromaticcompounds are effectively chlorinated with SnCl4/Pb(OAc)4 under mild conditions. The mixture is a selective chlorinating agent, particularly with polyalkylbenzenes, polycyclic aromaticcompounds and anisoles.

A survey study on electrophilic chlorination of aromatics with trichloroisocyanuricacid (TCICA) in Brønsted-acidic imidazolium ionic liquid [BMIM(SO3H)][OTf] is reported. The reactions are performed under very mild conditions (at ~50°C) and give good to excellent yields, depending on the substrates. Chemoselectivity for mono- v. dichlorination can be tuned by changing the arene-to-TCICA ratio and
