CATALYST FOR SYNTHESIS OF 1-(DIMETHYLAMINO)-3-ALKYL-2-PROPINES Russian patent published in 2010 - IPC B01J23/10 C07C211/06 C07C209/00

Abstract RU 2399413 C2

FIELD: chemistry.

SUBSTANCE: invention relates to catalysts, specifically to a catalyst for synthesis of 1-(dimethylamino)-3-alkyl-2-propines. The invention describes a method for synthesis of 1-(dimethylamino)-3-alkyl-2-propines through aminomethylation of 1-alkynes using bisamine (N,N,N¹,N¹-tetramethylmethanediamine) in an argon atmosphere in the presence of a catalyst in form of 6-hydrous samaric nitrate Sm(NO₃)₂*6H₂O.

EFFECT: said catalyst does not form explosive acetylides during aminomethylation of 1-alkynes in the presence of bisamine.
