Xenon iodide reactions

Perfluoropropyl iodide (8) formed difluoroiodoperfluoropropane in 60% yield upon reaction with xenon difluoride at 20 C.21... 

Reaction of Bridgehead Iodides with Xenon Difluoride General Procedure 1617... 

A regioselective iodoperfluoroalkylation of terminal alkynes (R—C = CH) has been reported, and is based on photolysis ofthe C—I bond in perfluoroalkyl iodides (Rp-I). Addition of the thus-formed RF" radical onto the alkyne afforded a vinyl radical that in turn abstracts an iodine atom from the starting Rp—I to form the end olefin R-C(I)= CH-Rf. A xenon lamp through Pyrex (hv > 300 nm) was used for the reaction, where aliphatic alkynes gave a better alkylation yield with respect to phenylacetylene [81],... 

A xenon trioxide solution may be convenientlj analyzed by adding iodide and dilute perchloric or sulfuric acid, and then titrating the liberated triiodide with thiosulfate. The net reaction is ... 

One piece of recent chemistry of [Xe2]+ has been its reaction with bromide and iodide ions in the presence of xenon gas, which yields the excited complexes XeBr and Xel respectively (107). 

POTASSIUM lODATE (7758-05-6) KIO, Noncombustible solid but many chemical reactions can cause fire and explosions. A strong oxidizer. Reacts violently with many materials, including reducing agents, hydrides, nitrides, and sulfides combustible materials, organic substances, manganese dioxide, arsenic, finely divided metals or carbon materials, hydrides of alkali or alkaline earth metalss, metal cyanides, metal thiocyanates, phosphonium iodide, red phosphorus, sulfides, sulfur, xenon tetrafluoride. Forms explosive compounds with solid organic matter. Mixture of powdered aluminum forms heat-, friction-, and shock-sensitive explosive. Attacks chemically active metals (e.g, aluminum, copper, zinc, etc.). Thermal deconposition, at temperatures above 1040°F/560°C, releases toxic iodine fumes. 

Scheme 21 Xenon difluoride-induced aryl-iodide reductive elimination from Pd complexes. The reaction is very general with regard to the aryl group involved...

This only known stable alkyliodine(III) difluoride is prepared by the reaction of xenon difluoride with excess methyl iodide and hydrogen fluoride at 20°. 

From measurement of the heat of reaction of xenon tetrafluoride with a solution of potassium iodide the heat of formation has been determined ...
