Photocyclization mechanism of halopyridinium salt tethered to arene: Flash photolysis observation of a pyridinium σ, cyclohexadienyl radicals, and a dihalide radical anion in aqueous solution

The photocyclization reactions of 2-halopyridinium salt tethered to arene have been studied. The photocyclization of 2-halophenethylpyridinium salts produced a six-membered heterocyclic product, pyrido[2,1-a]-3H,4H-isoquinolinium salt. The 2-halopyridiniu

exo-Selective Peripheral Cycloaddition Reactions of Pyridoisoindole

Pyridoisoindole cycloadds to olefinic dipolarophiles in a highly exo-selective fashion giving the kinetically controlled cycloadducts which gradually isomerize into the Michael adducts.With acetylenic dipolarophiles, the hydrogen-migrated cycloadducts are the only products.The mechanism of cycloadditions is discussed.

Flash photolysis observation of aryl, 2,3-dihydrocyclohexadienyl, and halogen anion radicals in aqueous solution: Photohomolytic radical cyclization of aryl halide

A thorough investigation of the transient species from the laser flash photolysis of haloarene tethered arenes has been performed. Some transient species in the laser photolysis of N-benzyl-2-halopyridinium and N-(2-halobenzyl)pyridinium bromides have been investigated as an effort to understand the photocyclized reaction mechanism as well as to know the properties of the transients themselves. Pyridinium σ, 2,3-dihydrocyclohexadienyl π, and halogen anion radicals are detected in the photolysis of a N-benzyl-2-halopyridinium salt (1 or 2) in water: the absorption maxima are 250, 310, and 355 (Br-Cl·-) nm, respectively. The lifetimes of 2-pyridinium σ radical, 2,3-dihydrocyclohexadienyl π, and bromine chloride (in the case of 1) anion radicals are 0.72 ms, 1.2 ms, and 9.3 μs, respectively. Phenyl σ, 2,3-dihydropyridinium π, and halogen anion radicals are also detected in the laser photolysis of an aqueous solution of a N-(2-halobenzyl)pyridinium salt (3 or 4): the absorption maxima are 250, 310, and 360 nm (Br2·-, in the case of 4), respectively. The lifetimes of the transient intermediates are 1.4 ms, 1.2 ms, and 10 μs, respectively. On the basis of the observation of these intermediates, their properties, and the reactant reactivities, a mechanism of the photohomolytic bond cleavage of carbon-halogen followed by radical arylation and hydrogen ejection is proposed for the intramolecular photocyclization of haloarene tethered arenes in water.
