Abstract

original image

S2O2, the unstable initial product of SO decomposition in the gas phase, has been trapped for the first time by complexation. With the isolation of the surprisingly stable thiirane S-oxide complex 1, it was further demonstrated that C2H4SO first decomposes after coordination to a metal. Ethylene is eliminated from 1 in toluene only at 110°C, whereupon the S2O2 complex 2 is formed.
