Synthesis of an (alkylperoxy)-λ3-iodane by the reaction of 1-hydroxy-1λ3,2-benziodoxol-3(1H)-one with 1,3-bis(trimethylsilyl)-3-methylbut-1-yne

Abstract

The BF₃-catalysed reaction of 1-hydroxy-1λ³,2-benziodoxol-3(1H)-one 1 with 1,3-bis(trimethylsilyl)-3-methylbut-1-yne 2b in dichloromethane under nitrogen afforded the peroxy-λ³-iodane, 1-[1,1-dimethyl-3-(trimethylsilyl)-prop-2-ynyl]peroxy-1λ³,2-benziodoxol-3(1H)-one, 5and its structure has been determined by single-crystal X-ray analysis.
