We report the discovery of the first double-barreled thermal rearrangement of a sulfonynamide and a methoxybenzyl to a nitrile and the first rearrangement of an SO(2) group from sulfonamide to ketoimine. The rearrangement occurs under surprisingly mild conditions (onset at 100 degrees C in the melt). [reaction: see text]
