with conventional vacuum systems due to vapor pressure limitations. Of particular interest are
processes that eliminate the generation of waste-streams. Here we show that He+O2 plasma can
drive the epoxidation of alkenes in solution, in a process that generates epoxides without oxidant
waste-streams, runs at room temperature and atmospheric pressure, and requires no catalyst. The
reactions between different reactive oxygen species generated in the plasma and the target alkene,
trans-stilbene in this study, have been identified and optimization of the plasma conditions within
the constraints of the current experimental set-up have led to yields of ~70%, which are of
preparative interest.
