The selective formation of aziridinofullerene and azafulleroid, which are isomers of the fullerene derivatives-introduced N1 unit, is achieved. The ionic aziridination is a very convenient and risk-free procedure compared with the conventional

Process for the preparation of asymmetrically substituted ureas, carbamates, thiocarbamates or substituted isocyanates by reaction of an adduct of isocyanic acid and a tertiary amine with a primary and secondary amine, an alcohol, a thiol or a compound having one or two non-cumulated olefinic double bonds, and a process for the preparation of N-mono- or N,N-disubstituted ureas by reaction of ammonium isocyanate with a primary or secondary amine in a diluent.

The reactions of long-chain diazo ketones and azides in adsorbed monolayers on inorganic solids were investigated and compared with the corresponding behaviour in monolayers at the air-water interface. The isolated products indicate that reaction of photochemically generated intermediates occurs both with co-adsorbed water and with hydroxyl groups on the solid surface. In the case of 1-diazo-2-oxoheptadecane, for example, the products of these two reactions are heptadecanoic acid and a surface-grafted long-chain ester. The latter can be removed as methyl heptadecanoate by ester exchange using methanolic HCl. Pronounced differences were observed between alumina, silica gel and fumed silica as supports, and were attributed to differences in the amount of adsorbed H2O and in the density of surface hydroxyl groups.
