Reactions of 1-(2-alkoxyphenyl)alkaniminyl radicals
Reactions of 1-(2-alkoxyphenyl)alkaniminyl radicals were studied. Generation of the iminyls 1d and 1e by standard methods in the gas-phase by flash vacuum pyrolysis (FVP) gives rise to 1,3-benzoxazines 18 and 22 by a mechanism which probably involves a 1,6-hydrogen atom translocation. The results showed that the dealkylation is an integral part of the reaction mechanism and not a subsequent reaction of 2-alkoxybenzonitriles.

Palladium-catalyzed direct acylation of ketoximes and aldoximes from the alcohol oxidation level through C-H bond activation
A highly efficient palladium-catalyzed oxidative ortho-acylation of O-methyl ketoximes and O-methyl aldoximes with benzylic and aliphatic alcohols from the alcohol oxidation level is described. This protocol potentially provides new opportunities to use readily available alcohols as starting materials for catalytic reactions, and represents a catalytic alternative to transcend the barriers imposed by classical Friedel-Crafts acylation. A highly efficient palladium-catalyzed oxidative ortho-acylation of O-methyl ketoximes and O-methyl aldoximes with benzylic and aliphatic alcohols from the alcohol oxidation level is described.
