RADICAL TRAP IN FLUORIDATION OF IODONIUM SALT
-
Page/Page column 24-25, (2008/06/13)
Decomposition of iodonium salts by a free radical process has been identified as a significant factor in the observed yield variability of fluoridation reactions using said iodonium salts. Accordingly, the inclusion of a free radical trap in the reaction mixture blocks the radical chain decomposition pathway for iodonium salts such that only the reaction leading to fluoridation can occur and the yield of aryl fluoride becomes high and reproducible. The reaction may also be carried out on solid phase. In both the solution and the solid phase the preferred method of the present invention is radiofluoridation.

Reactions of RYbI (R = Me, Et, Ph) with organotin oxides and acetates) involve cleavage of the Sn-O bonds to form tetrasubstituted stannanes mostly as single or main reaction products (yields 65-96 percent). A similar results was obtained in reaction of PhYbI with diphenyltin sulfide (yield 93 percent). However, reactions of RYbI (R = Me, Et, Ph) with Bu2SnO, followed by hydrolysis of the reaction mixtures lead to hydroxystannanoxanes Bu2RSnOH in 66-75 percent yields.
