Catalytic Activation of C−H and C−C Bonds of Allylamines via Olefin Isomerization by Transition Metal Complexes
摘要:
The metal-catalyzed reaction of olefins with allylamines bearing coordination sites (2-pyridyl groups) was studied. With Ru-3(CO)(12) as catalyst, activation of C-H bonds led to the formation of ketimines that were hydrolyzed to give asymmetric ketones. With [(C8H14)(2)RhCl](2), both C-H and C-C bonds were activated and symmetric ketones were formed on hydrolysis. The reaction involves double bond migration of the allylamine to form an aldimine.

A direct synthesis of ketones by the nickel-catalyzed deaminative cross-coupling of alkylpyridinium salts with thiopyridine esters has been reported. The reaction works well for both primary and secondary amines. This approach affords a highly valuable vista for the facilesynthesis of ketones from easily accessible feedstock chemicals. The utility of this method is demonstrated through the functionalization

[GRAPHICS]Dehydrogenation and subsequent transimination of primary amines offer a new pathway for C-H bond activation, ortho-alkylation, and C-C bond activation to afford a variety of ketones in the reaction of l-alkene by a cocatalyt system of Rh(I) and 2-amino-3-picoline.
