The silver catalyzed oxidative decarboxylation of carboxylic acids by aroylperoxides, percarbonates and perborate provides new sources of alkyl radicals useful for selective substitution of lepidine.

Evidence for a molecule-induced homolysis of dimethyldioxirane by several classes of organic compounds (alkanes, alkenes, ethers, alcohols, aldehydes, iododerivatives) is reported. Carbon-centered radicals, arising from alkanes, ethers, and aldehydes, are trapped by CBrCl3 or protonated quinolines. The dramatic influence of oxygen in these reactions, as well as the formation of products of induced homolysis of the dioxirane by carbon-centered radicals (CH4, CH3OH, CH3COOCH3, ROCOCH3, CH3COOCH2COCH3), strongly supports a radical mechanism. With alkenes and iodo derivatives the induced homolysis would lead to diradical intermediates, whose very fast fragmentation would prevent detection, but circumstantial evidence supports a radical mechanism.
A Convenient Synthesis of Substituted Quinolines by Thermal Electrocyclic Rearrangement of o-Vinyl Anils under Nonacidic Conditions

Anils 8a-g (Table II) underwent smooth rearrangement and oxidation to the quinolines 9a-g at 155-200 deg C via formation of the 2-3 carbon-carbon bond.These cyclizations proceeded in high yields under nonacidic conditions.It was often possible to prepare
