                                    3-Aryl-2,1-benzisoxazoles and its salts underwent reductive cleavage of the N-O bond leading to 2-aminobenzophenones with bakers' yeast under non-fermenting conditions in aqueous media. The procedure gives excellent yields of 2-alkylamino- and 2-aminobenzophenones.
