Porter, Ashlin G.; Hu, Hanfeng; Liu, Xuemei; Raghavan, Adharsh; Adhikari, Sarju; Hall, Derrick R.; Thompson, Dylan J.; Liu, Bin; Xia, Yu; Ren, Tong published the artcile< Heptamolybdate: a highly active sulfide oxygenation catalyst>, Application In Synthesis of 699-12-7, the main research area is crystal structure heptamolybdate preparation sulfide oxidation catalyst kinetics sulfone.
The sulfide oxygenation activities of both heptamolybdate ([Mo7O24]6-, [1]6-) and its peroxo adduct [Mo7O22(O2)2]6- ([2]6-) were examined in this contribution. [Mo7O22(O2)2]6- was prepared in a yield of 65% from (NH4)6[Mo7O24] (1a) upon treatment of 10 equiv of H2O2 and structurally identified through single crystal x-ray diffraction study. (Bu4N)6[Mo7O22(O2)2] (2b) is an efficient catalyst for the sequential oxygenation of Me Ph sulfide (MPS) by H2O2 to the corresponding sulfoxide and subsequently sulfone with a 100% utility of H2O2. Surprisingly, (Bu4N)6[Mo7O24] (1b) is a significantly faster catalyst than 2b for MPS oxygenation under identical conditions. The pseudo-first order kcat constants from initial rate kinetics are 54 M-1 s-1 and 19 M-1 s-1 for 1b and 2b, resp. Electrospray ionization mass spectrometry (ESI-MS) study of 1b under the catalytic reaction conditions revealed that [Mo2O11]2- is likely the main active species in sulfide oxygenation by H2O2.
