NITRATION OR CARBOXYLATION CATALYSTS

In the presence of an imide compound (e.g., N-hydroxyphthalimide) shown by the following formula (1): ???wherein R1and R2represent a hydrogen atom, a halogen atom, an alkyl group, an aryl group and a cycloalkyl group, and R1and R2may bond together to form a double bond, or an aromatic or non-aromatic ring, and Y is an O or OH, and n denotes 1 to 3;, a substrate is allowed to contact with at least one reactant selected from (i) a nitrogen oxide and (ii) a mixture of carbon monoxide and oxygen to be introduced with at least one functional group selected from a nitro group and a carboxyl group. The nitrogen oxide includes, for example, a compound represented by the formula NxOy(e.g., N2O3, NO2). The substrate includes, for example, a compound having a methine carbon atom (e.g., adamantane), a compound having a methyl group or a methylene group at an adjacent moiety of an aromatic ring. According to such reaction, the substrate can be efficiently nitrated or carboxylated even in a mild or moderate condition.

Ozone-mediated nitration of adamantane and derivatives with nitrogen dioxide: Selectivity in the hydrogen abstraction by nitrogen trioxide and subsequent coupling of the resulting carbon radicals with nitrogen dioxide

In the presence of ozone at -78°C, nitrogen dioxide reacts rapidly and selectively with adamantane at a bridgehead position to give the corresponding nitro derivative as the sole major product. The relative reactivity has been determined for a series of 1-substituted adamantanes, which reveals that electron-withdrawing substituents exert a considerable influence on the ease of substitution at the γ-position as well as the distribution of the N- and O-functionalized products. The results may be rationalized in terms of the initial hydrogen abstraction by nitrogen trioxide, followed by rapid trapping of the resulting adamantyl radicals with nitrogen dioxide.
