, p. 2427 - 2428 (2007/10/02)
The photosubstitutions of 2-fluoro-4-nitroanisole with several amines are studied from the preparative and the preliminary mechanistic points of view.The possible usefulness of this structure as biochemical photoprobe is discussed.

The photosubstitutions of 2-fluoro-4-nitroanisole with several amines are studied.The preparative results, the thermal stability of the photochemical substrate, and the limiting quantum yield values obtained from photoreactions with several nucleophiles suggest the possible usefulness of 2-fluoro-4-nitrophenyl ethers as biochemical photoprobes.

Irradiation of 3,4-dimethoxy-1-nitrobenzene in the presence of butylamine leads to the formation of both possible photosubstitution products, i.e., 2-methoxy-4-nitro-N-butylaniline and 2-methoxy-5-nitro-N-butylaniline with the predominance of the latter.Regioselectivity of the reaction as measured by molar ratio of the two isomeric products varies with pH of the solution, ranging from 3:1 at pH 10 to 12:1 at pH 12.The results are discussed in view of possible use of 3,4-dimethoxy-1-nitrobenzene moiety as a lysine-directed photoaffinity probe.
NITROPHENYL ETHERS AS POSSIBLE PHOTOAFFINITY LABELS. THE NUCLEOPHILIC AROMATIC PHOTOSUBSTITUTION REVISITED.

The photoreactions of nitrophenyl ethers with simple primary and secondary amines show a remarkable nucleophile influence on the reaction orientation.Calculations indicate a change from charge controlled to frontier orbital controlled reactions moving from smaller to larger amines.
