Lewis/Bronsted acid activation plays a key role in hypervalent iodine reagent-mediated reactions. In addition to generally accepted cis-activation or trans-activation, this study reveals another important Lewis/Bronsted acid activation mode, the double-activation. Different from the generally proposed iodine(III)iranium SN2 mechanism, the hypervalent difluoro-iodoarene-promoted fluorocyclization of unsaturated alc. prefers to undergo the metathesis mechanism via an iodine(III)-π intermediate. The results came from multiple reactions, including the reaction of 1-Iodo-4-methylbenzene(cas: 624-31-7Product Details of 624-31-7)
1-Iodo-4-methylbenzene(cas: 624-31-7) is used in wide range of medicals industrial applications as well as in pharmaceutical intermediates, polarizing films for Liquid Crystal Display (LCD) chemicals.Product Details of 624-31-7
