alpha-Tertiary aminesWe demonstrated a ruthenium-catalyzed regioselective allylic amination of tertiary allylic esters with various amines using [Cp*Ru(CH3CN)(3)][PF6]/5,5'-dimethyl-2,2'-bipyridine (5,'-diMe-2,2'-bpy) and related ruthenium catalytic systems, and successfully obtained a ...
TERTIARY AND SECONDARY AMINES AS ALPHA-2 ANTAGONI
The present invention relates to a method for preparing a heterogeneous catalyst in the presence of a tertiary α- carbon atoms by primary amines with ammonia tertiary alcohol, which as a catalyst in the presence of a non-porous and non-zeolitic aluminosilicate of the reaction, the ...

A practical, catalytic entry to alpha,alpha,alpha-trisubstituted (alpha-tertiary) primary amines by C-H functionalisation has long been recognised as a critical gap in the synthetic toolbox. We report a simple and scalable solution to this problem that does not require any in situ protection ...
amineshydroaminationsulfamatesAn efficient and mild trifluoromethanesulfonic acid-catalyzed hydroamination of unfunctionalized alkenes to afford alpha-tertiary amine derivatives at temperatures as low as room temperature is reported. 2,2,2-Trifluoroethyl sulfamate was found to be the optimal nitrogen source...
Some salts of tertiary amines tend to dissociate reversibly when heated. However, the compounds of the present invention preferentially decompose, irreversibly, to generate carbon dioxide when heated.Ibrahim S. BecharaDewey G. HollandUSUS4165412 1978年8月28日 1979年8月21日 Air Products And ...
