The direct synthesis of symmetrical disulfides and diselenides by metal–organic framework MOF-199 as an efficient heterogenous catalyst†
Abstract
A highly crystalline porous copper-based metal–organic framework MOF-199 was synthesized, and characterized by several techniques, including XRD, EDX, SEM, and FT-IR. MOF-199 was used as an efficient catalyst for the one-pot and efficient synthesis of organic dichalcogenides from aryl halides (–OTs) and elemental sulfur and selenium in polyethylene glycols (PEGs). A variety of disulfides and diselenides can be obtained in good to excellent yields of up to 98% in a relatively short reaction time.
