Methyltriphenoxyphosphoniumiodide (MTPI) is an effective dehydration and dehydrohalogenation reagent under mild conditions when 1,3-dimethylimidazolidin-2-one is used as an aprotic solvent in place of the more normally used hexamethylphosphoric triamide (HMPT). Since previously suggested mechanisms had proposed alcohol–HMPT interaction as an important mechanistic step, this result coupled with comparative
