Synthesis of ¦Â-Iodo(III)enol carboxylates, I (R1 = Et, Me, Bu, t-Bu; R2 = Et, Ph, thiophen-2-yl, etc.; R3 = 4-oxopentanoyl, benzoyl, 2,2-dimethylpropyl, etc.) phosphates, I (R3 = diethoxyphosphoroso, diphenoxyphosphoroso, dimethoxyphosphoroso, diphenylphosphoroso) and tosylates I (R3 = Ts) can be efficiently performed through regio- and stereoselective iodo(III)functionalization of alkynes R1CCR2. The combination of 1,2-benziodoxole, 1-chloro-1,3-dihydro-3,3-bis(trifluoromethyl)- and silver salt has proven to generate a versatile cationic iodine(III) electrophile to activate alkynes and engage various carboxylic acids R4COOH (R4 = Me, Ph, 2-phenylethenyl, etc.), tri-Et phosphate and p-toluenesulfonic acid as nucleophiles. The ¦Â-iodo(III)enol esters serve as starting materials for the synthesis of multisubstituted alkenes I through sequential cross-coupling of the C-I(III) and C-O bonds.
