“…[1][2][3][4][5] As for the application of trivalent organoantimony compounds (stibanes), a wide variety of reactions such as self-coupling reactions, 6,7) cross-coupling reactions, [8][9][10][11][12][13] photoreaction, 14) and asymmetric reactions with optically active organoantimony compounds [15][16][17][18][19] have been reported during the last two decades. On the other hand, the conversion of benzoin into benzil has been accomplished by oxidation with a variety of reagents; i.e., bismuthane oxide, 20) bismuthane imides, 21) alumina-supported copper sulfate under microwave irradiation, 22) and the Burgess reagent, 23) and by transition metal-catalyzed oxidation with bismuth nitrate-copper acetate, 24) aerobic oxygen, 25,26) diacetoxyiodobenzene, 27) and allyl diethyl phosphate.…”
