Rhodium(I)-catalyzed cycloisomerization of benzylallene-alkynes through C-H activation

The efficient RhI-catalyzed cycloisomerization of benzylallene-alkynes produced the tricyclo[9.4.0.03,8] pentadecapentaene skeleton through a C sp 2-H bond activation in good yields. A plausible reaction mechanism proceeds via oxidative addition of the acetylenic C-H bond to RhI, an ene-type cyclization to the vinylidenecarbene- RhI intermediate, and an electrophilic aromatic substitution with the vinylidenecarbene species. It was proposed based on deuteration and competition experiments.
