Figure 3.
Fig. 3. Proposed catalytic mechanisms of TEAS and HVS based
on the TEAS crystal structures. (A) through (F) are reaction
steps common to both TEAS and HVS. (G[1]) through (I[1]) are
specific to TEAS, and (G[2]) through (I[2]) are^ specific to
HVS. Carbocations are yellow, protons are light blue, and
aromatic quadrupoles are indicated with purple lines.
Intermediate^ structures are numbered according to the acyclic
precursor, FPP (A). Figure was generated with Chem3D
(CambridgeSoft).
