A radical deoxychlorination of cesium oxalates has been developed for the preparation of hindered secondary and tertiary alkyl chlorides. The reaction tolerates a number of functional groups, including ketones, alcohols, and amides, and provides complementary reactivity to standard deoxychlorination reactions proceeding by heterolytic mechanisms. Preliminary studies demonstrate that the developed conditions can also be applied to deoxybromination and deoxyfluorination reactions.

(Diacyloxyiodo)arene was treated with electron-deficient olefins in the presence of hydrogen donor such as 1,4-cyclohexadiene to give the reductive addition products via alkyl radical through the radical decarboxylative pathway in good yields.Moreover, this system was able to generate either alkoxycarbonyl radicals or alkyl radicals with benzene, which was prepared from alcohol, oxalyl chloride, and (diacetoxyiodo)benzene via two steps, depending on reaction conditions.These radicals were also utilized for C-C bond formation with electron-deficient olefins.
Alkylation of Aromatic Heterocycles with Oxalic Acid Monoalkyl Esters in the Presence of Trivalent Iodine Compounds

Aromatic heterocycles containing nitrogen atoms were easily alkylated with the half esters of oxalic acid, which were prepared from alcohols, in the presence of benzene via radical decarboxylative pathways.This is the first method for the alkylation of aromatic heterocycles with alcohols via the formation of half esters of oxalic acid.
