Nickel complex-catalysed reactions of butadiene with amines

Abstract

SO9 5NH)Summary Octadienyl and butenyl substituted amines reported. Tertiary phosphine complexes of palladium(0) have been shown to catalyse the reaction of buta-1,3-diene with methanol and phenol to give l-methoxyocta-2,7-diene and l-phenoxyocta-2,7-diene, respective1y.l Similar reactions have been demonstrated with primary and secondary A NUMBER of palladium complex-catalysed reactions of amines, carboxylic acids,2 9 3 and active-methylene and active-hydrogen compounds with buta-1,3-diene have been -methine compounds.4 have been prepared by reaction of primary and secondary amines with butadiene catalysed by nickel( 0) complexes.

Efficient Gold‐Catalyzed Hydroamination of 1,3‐Dienes

“…Transition-metal-catalyzed hydroamination of conjugated dienes is not new: a nickel-catalyzed process was reported as early as 1971. [11] Since then, there have been a few examples in which Pd 0 , Rh I , Rh III , or Co II is used. [12] Telomerization often occurs in the palladium-and nickel-catalyzed reactions.…”

Efficient Gold‐Catalyzed Hydroamination of 1,3‐Dienes

“…The resulting allylic amine10 products are important precursors in organic synthesis and are encountered in many natural products.
