Direct decarboxylative radical allylation of aliphaticcarboxylicacids is described. With K2S2O8 as the oxidant and AgNO3 as the catalyst, the reactions of aliphaticcarboxylicacids with allyl sulfones in aqueous CH3CN solution gave the corresponding alkenes in satisfactory yields under mild conditions. This site-specific allylation method is applicable to all primary, secondary, and tertiary alkyl

We report herein an efficient and general method for the decarboxylative azidation of aliphaticcarboxylicacids. Thus, with AgNO3 as the catalyst and K2S2O8 as the oxidant, the reactions of various aliphaticcarboxylicacids with tosyl azide or pyridine-3-sulfonyl azide in aqueous CH3CN solution afforded the corresponding alkyl azides under mild conditions. A broad substrate scope and wide functional

C(sp(3))-C(sp) bondformations are of immense interest in chemistry and material sciences. We report herein a convenient, radical-mediated and catalytic method for C(sp(3))-C(sp) cross-coupling. Thus, with AgNO(3) as the catalyst and K(2)S(2)O(8) as the oxidant, various aliphatic carboxylic acids underwent decarboxylative alkynylation with commercially available ethynylbenziodoxolones in aqueous solution

The silver-catalyzed decarboxylativetrifluoromethylation of aliphatic carboxylicacids is described. With AgNO3 as the catalyst and K2S2O8 as the oxidant, the reactions of aliphatic carboxylicacids with (bpy)Cu(CF3)3 (bpy = 2,2'-bipyridine) and ZnMe2 in aqueous acetonitrile at 40 °C afford the corresponding decarboxylativetrifluoromethylation products in good yield. The protocol is applicable to
