Figure 3.
Stepwise radical dimerization of the reactive thiocarbonyl S-methanide 8. Computed enthalpies (free energies in parentheses) at 298 K at the SMD(tetrahydrofuran)/M06-2X/6-311+G(2df,p)//M06-2X/6-31G(d) level of theory. The species 12E–I are all biradical intermediates in the reaction mechanism and should be able to interconvert readily.
