2-Iodobenzoic acid → 2-Iodobenzoyl chloride

Participants

Reaction Steps

Ortho-iodobenzoic acid was reacted with excess thionyl chloride for 3 hours at reflux, and thionyl chloride was distilled off under reduced pressure to obtain ortho-iodobenzoic acid chloride. This was reacted with allyl alcohol in a dichloromethane solvent in the presence of a triethyl amine catalyst to obtain allyl ortho-iodobenzoate. The yield after purification by distillation or like process was repeated was 73%.
