inexpensive NiII/Zn couple enables the allylation of primary, secondary, and electron‐deficient amines without the need for glove‐box techniques. Under mild conditions, primary and secondary aliphatic amines react smoothly with a range of allyl alcohols, giving secondary and tertiaryaminesefficiently. This “totally catalytic” method can also be applied to electron‐deficient nitrogen nucleophiles; the
of noble metal catalysts in homogeneouscatalysis has been well established. Due to their price and limited availability, there is growing interest in the substitution of such precious metal complexes with readily available and bio‐relevant catalysts. In particular, iron is a “rising star” in catalysis. Herein, we present a general and selective iron‐catalyzed monoisomerization of olefins, which allows

The synthesis of unsaturated, unprotected imidazolidinones via an aza‐Heck reaction is described. This palladium‐catalyzed process allows for the cyclization of N‐phenoxy ureas onto pendant alkenes. The reaction has broad functional group tolerance, can be applied to complex ring topologies, and can be used to directly prepare mono‐ and bis‐unprotected imidazolidinones. By addition of Bu4NI, dihydroimidazolones

A palladiumcomplex bearing chiral (hydroxyalkyl)ferrocenylphosphine ligand was found to be a highly regio-and stereoselective catalyst for the asymmetric allylic amination of 2-butenyl acetates with benzylamine, the nucleophilicattack of the amine taking place selectively on the more substituted end of the π-allylpalladium intermediate to give optically active 3-benzyamino- 1-butene of up to 84%
