Heterogeneous Chitosan@copper Catalyzed Selective C(sp<sup>3</sup>)–H Sulfonylation of Ketone Hydrazones with Sodium Sulfinates: Direct Access to β-Ketosulfones
The exploration of inexpensive and stable heterogeneous catalysts for C–S coupling reactions remains a challenging issue. Herein, we successfully prepared a new biomass-derived copper catalyst and applied it to the selective C(sp<sup>3</sup>)–H-directed sulfonylation of ketone hydrazones...
