Reagent for protection of boronic acids as N-methyl-O,O-diethanolamine esters (cf Diethanolamine, A13389). The resulting derivatives have been converted to fluoroaromatics using cesium fluoroxysulfate: Synlett, 761 (1990); Tetrahedron, 48, 8073 (1992).

The boronic esters are also stable in the presence of organometallic (e.g. lithium derivatives): J. Org. Chem., 54, 4734 (1989).
