Controlling Factors Determining the Regiochemistry of Intramolecular Alkoxymercuration. -The regioselectivity of intramolecular alkoxymercuration of compounds ( I) is closely related to the Hammett constants of the substituents on the benzene ring and is further effected by the solvent leading to t

In 1964 Chapman et al have reported a photorearrangement of a,B-unsaturated nitro-9--s olefins to a-oximino ketones. 2 Thereafter, a large number of examples of the nitro to nitrite rearrangement have been shown in the photochemistry of nitro-olefins 3 and of nitro aromatic 1058 (1971); c) 0. L.
The coiling effect should not be invoked to account for the fact that the basicity of alkyl-amines and acidity of alkanols in the gas phase do not fall off as the chain length increases. For alkanols, the reason lies in the formation of an intramolecular hydrogen bond between a C-H group and the oxy
