The first examples of titanium-catalyzed hydroaminoalkylation reactions of ethylene with secondary amines are presented. The reactions can be achieved with various titanium catalysts and they do not require the use of high pressure equipment. In addition, the first solid-state structure of a titanapyrrolidine that is formed by insertion of an alkene into the Ti?C bond of a titanaaziridine is reported.

It is highly desirable to develop efficient heterogeneous photocatalysts for organic reactions. Here, we show the preparation and catalytic performance of a novel TiO2 (P25) supported Cu and Mo photocatalyst (Cu-Mo/TiO2) for N-alkylation of amines with alcohols under UV irradiation at room temperature. A variety of aromatic and aliphatic amines were selectively converted into the corresponding secondary amines or tertiary amines in moderate to excellent yields without the addition of any co-catalysts such as bases and organic ligands. Noteworthy, this catalytic system is feasible in the alkylation of anilines containing halogen substituents with alcohols and the yields of the desired products are up to 95%.

Reaction of anils with alkyl halides under high pressure (10 kbar) was studied. Alkylation in polar media (dioxane or acetonitrile) followed by hydrolysis yields pure N-monoalkylanilines in high yields. Optimum conditions for high-pressure alkylation were found.
