“…7,9,14,18,19 Among others, the catalytic efficiency of lacunary and transition metal-substituted Keggin-type polyoxotungstates in the oxidation of S-compounds has already been demonstrated in several reports. 27,[37][38][39][40][41][42][43][44][45][46] Our previous experience with the use of the undecatungstoboromanganateIJIII) anion, [BW 11 MnIJH 2 O)O 39 ] 6− (BW 11 Mn), in oxidative catalysis has shown that it is an efficient and robust catalyst for the oxidation with H 2 O 2 of several types of substrates, 28,31,[47][48][49] suggesting that it could be a good candidate to be used for the oxidation of organosulfur compounds. Moreover, our research group has developed a catalytic oxidation system of organosulfur derivatives under mild conditions using metalloporphyrin complexes.…”
