Abstract

Described here is the first application of plasma-enhanced chemical vapor deposition (PE-CVD) to thesynthesis of catalytically active materials, prepared by covering Merrifield resin beads with an oxygen-containing fluorocarbon thin film deposited in a hexafluoropropene-O2plasma. Such modified resinscatalyze both the selective epoxidation of trans--methylstyrene and its double oxidative cleavage tobenzaldeyde in organic-water biphasic media at room temperature, using potassium monoperoxysulfate(KHSO5) as the terminal oxidant. Interestingly, the epoxide/benzaldehyde product ratio strictly dependson the conditions adopted for catalyst generation. This, coupled with evidence for the presence of carbonylgroups on the surface of treated resins, point to dioxirane and singlet oxygen (1O2)-mediated oxidations;1O2being produced in the decomposition of KHSO5. Compared to traditional synthetic procedures toobtain similar catalytic active materials, the application of PE-CVD is eco-sustainable and less expensive.Also, the activity of catalysts can be fully restored upon iterative re-treatment of the exhausted resin.
