The mechanochemical reaction of C₆₀and Bi(NO₃)₃·5H₂O

Recent Advances in Mechanochemical Organic Synthesis

“…C▬N bond forming reactions were paid larger attention to. Mechanochemical nitration reactions of aromatics are extended to various reagents: NaNO 3 in conjunction with MoO 3 as an additive [43], BiNO 3 with MgSO 4 [44], as well as BiNO 3 alone was applied for nitration of fullerene C 60 [45]. Amine guanylation with N,N′-Di-Boc-1H-pyrazole-1-carboxamidine [46] and facile Boc deprotection was achieved with TsOH [47].…”

Mechanochemical sulfonation of aromatic compounds using NaHSO4·H2O/P2O5

“…[16][17][18][19][20][21][22] As a green alternative to traditional solution-based synthetic approaches, mechanochemical organic synthesis exhibits many advantages over its liquid-phase counterpart in terms of higher product yields, better selectivity, shorter reaction times, simple work-up procedures, elimination of harmful organic solvents, and so on. During our exploration of high-speed ball milling (HSBM) reactions, [23][24][25][26][27][28][29] we recently found that arenes could be converted into diarylsulfones using 3CdSO 4 •xH 2 O/P 2 O 5 as the sulfonating reagent, and noted that aromatic sulfonic acids were formed as by-products during the reaction. 29 We speculated that a higher yield of the aromatic sulfonic acid could be achieved by optimizing the HSBM conditions.…”
