Photoinduced electron transfer (PET) initiates radical-cation Diels ± Alder reactions between indole and exocyclic dienes. As catalysts, triarylpyrylium tetrafluoroborates are used. The products are [b]-anellated tetrahydrocarbazoles, which are not accessible through neutral cycloadditions. The resu

✦ Synopsis
AM1 molecular orbital method uing the unrestricted Hartree-F&( UHF) calculations has been applied to investigkte the thermal reaction of cyclohexadiene and methyl crotonate. The calculated reed& iqdicate that the thermal Diels-Alder reaction proceeds to product through the concerted path and two radical pathways.

## Abstract Thermal decomposition of cyclopentadiene to __c__‐C~5~H~5~ (cyclopentadienyl radical) + H (1) and the reverse bimolecular reaction (−1) are studied quantum‐chemically at the G2M level of theory. The dissociation pathway has been mapped out following the minimum energy path on the potent
## Abstract The reaction mechanism of OBrO with OH has been studied using the B3LYP/6‐311+G(d,p) and the high‐level electron‐correlation CCSD(T)/6‐311+G(d,p) at single‐point. The results show that the title reaction could probably proceed by four possible schemes, generating HOBr+O~2~, HBr+O~3~, Br
