Mixed alkylaryl BiIII derivatives have been prepared by both anionic and free radical methods. The thermal stability of these compounds permits them to be used in the presence of cupric acetate for the alkylation of amines. Trialkylbismuth compounds can also be used in the same way.

Abstract A one-pot, simple, selective, and efficient protocol for the synthesis of aromatic secondary amines from various nitro arenes and nitriles in the presence of 10% Pd/C catalyst under H2 at atmosphericpressure and ambient temperature in tetrahydrofuran is illustrated. The scope and limitations of this method have been examined.

o) titanium precatalyst for the anti-Markovnikov hydroamination of alkynes is reported. Hydroamination of terminal and internal alkynes with primary alkylamines, arylamines, and hydrazines is promoted by 5–10 mol % of Ti catalyst. Various functional groups are tolerated including esters, protected alcohols, and imines. The in situ generated complex shows comparable catalytic activity, demonstrating

development of synthetic methodologies where nucleophilicaddition reactions to imino carbons are utilized in crucial steps. This article summarizes double nucleophilicaddition reactions with alpha,beta-unsaturated aldimines, addition reactions using alkynyl imines, "umpoled" reactions of alpha-imino esters, and the use of iminium salts as reactive electrophiles.
