-alkyl iodides readily reacted with a variety of alkenes in methanol at room temperature under the influence of metallic tin(0)-silver(I) acetate of metallic tin(0)-copper(I) chloride to afford the corresponding addition products, - alkylated iodides, in good to excellent yields. This addition reaction was also promoted by the use of a metallic tin(0)- aluminium(0) reagent, though gentle heating was

The first example of visible light promoted fluoroalkylation reactions initiated via noncovalent interactions between acetone and fluoroalkyl iodides is presented. The reaction system features synthetic simplicity, mild reaction conditions without any photoredox catalyst, and high functional group tolerance. A wide range of substrate scopes such as alkenes, alkynes and (hetero)arenes were all compatible

With the combination of p-methoxybenzene-diazonium tetrafluoroborate with TiCl3 as the initiator, a wide range of halogen atom-transfer radical addition or cyclization reactions could be efficiently implemented in aqueous solution at room temperature.
New Efficient Palladium-Catalyzed Perfluoroalkylation of Carbon-Carbon Multiple Bonds with<i>F</i>-Alkyl Iodides. An Expedient Route to<i>F</i>-Alkylated Alkyl and Alkenyl Iodides
A variety of alkenes and alkynes efficiently undergo the perfluoroalkylation with F-alkyl iodides in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium(0) in hexane to give good yields of the corresponding F-alkylated alkyl and alkenyl iodides, respectively.

Perfluoroalkyl iodides, in the presence of a catalytic amount of Ti0 generated in situ, add to alkenes in dimethoxyethane solvent to afford 1-(n-perfluoroalkyl)-2-iodoalkanes in moderate to good yields. 1-Alkenes, 1-alkynes and alkenes containing bromo or ester substituents gave yields of the 1:1 addition adducts with n-perfluoroalkyl iodides. 1-Alkenes containing ketone or alcohol groups gave low
