Optimized syntheses of iodylarenes from iodoarenes, with sodium periodate as the oxidant. Part II

Abstract

An improved method is reported for optimized preparations of iodylarenes, ArIO 2 , from iodoarenes, ArI, using NaIO 4 as the oxidant dissolved in boiling 30% (v:v) aq. CH 3 COOH solutions. The former reaction times, reported in Part I, 1 were shortened from 8-16 hours to 3-6 hours, with preserving the same good yields and high purities of the crude final products, ArIO 2 . A considerably improved method of preparing "2-iodosylbenzoic acid" is also reported in this paper. See also our Warning submitted in Experimental.
