Preparation of 1,1′-Oxy-bis(3,3-bis(trifluoromethyl)-3(1H)-1,2-benziodoxole) and 2-(N-(p-Toluenesulfonyl)imino)iodobenzylmethyl Ether

Conditions for improved preparation of the crystalline iodine(III) reagents [1,2-C6H4(C(CF3)2OI)]2O and 1,2-C6H4(CH2OMe)(I=NTs) are presented together with their x-ray structures. The former is prepared by hydrolysis of 1,2-C6H4(C(CF3)2OICl (x-ray) and allows the preparation of cyclic sulfates from alkenes; the latter fashions sulfamidate under related conditions.
