资源简介：
The formal [8 + 2] cycloaddition reaction between alkynyl
Fischer
carbene complexes and tropothione leads to the regioselective formation
of novel 3aH-cyclohepta[b]thiophene
carbene complexes. Computational DFT calculations indicate that the
process proceeds stepwise via antiaromatic zwitterionic intermediates
