Tuning the Electron Acceptability of the [Mo6S8] Cluster Core by Decorating It with Methyl Groups on the Face‐Bridging µ3‐Sulfides

The physical properties of ultrathin transition metal dichalcogenides (2D-TMDCs) make them promising candidates as active nanomaterials for catalysis, optoelectronics, and biomedical applications. Chemical modification of TMDCs is expected to be key in modifying/adding new functions that will help make such promise a reality. We present a mild method for the modification of the basal planes of 2H-MoS2 and WS2. We exploit the soft nucleophilicity of sulfur to react it with maleimide derivatives, achieving covalent functionalization of 2H-TMDCs under very mild conditions. Extensive characterization proves that the reaction occurs through Michael addition. The orthogonality and versatility of the thiol–ene “click” chemistry is expected to allow the à la carte chemical manipulation of TMDCs.

Tuning the Electron Acceptability of the [Mo₆S₈] Cluster Core by Decorating It with Methyl Groups on the Face‐Bridging µ₃‐Sulfides

Abstract: Methylation of the molybdenum sulfide cluster unit [Mo 6 S 8 (PEt 3 ) 6 ] (1) with CH 3 OTf resulted in the formation of mono-and dimethylated cluster units, [Mo 6 S 8-x (SCH 3 ) x -(PEt 3 ) 6 ]OTf·yCH 2 Cl 2 {[2]OTf·0.5CH 2 Cl 2 (x = 1, y = 0.5) and [a]
