Rh(II) carbene SH insertion into H2S via the stepwise mechanism

The mechanism of Rh(II) carbene SH insertion into H2S in gas phase has been studied by B3LYP functional. Calculation results showed that the Rh(II) carbene SH insertion into H2S took only stepwise channels and no concerted channels had been located, which was different from the Rh(II) carbene CH and OH insertions.
