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
Amines reacted with primary alcohols in the presence of a platinum complex catalyst at 120–180 °C to give N-alkylated or N-allylated compounds.
在120-180°C下,胺类在铂络合物催化剂的存在下与伯醇反应,生成N-烷基化或N-烯丙基化产物。

A new synthesis of 1,4-benzodiazepines and 1,4-benzodiazepin-5-ones is reported. The Pd-catalyzed coupling of N-allyl-2-aminobenzylamine derivatives with aryl bromides affords the heterocyclic products in good yield, and substrates bearing allylic methyl groups are transformed to cis-2,3-disubstituted products with >20:1 dr.

Radical reactions! Efficient methods for the generation of CF3‐containing epoxides and aziridines have been developed (see scheme). A variety of allylicalcohols and allylicamines were transformed into the corresponding epoxides and aziridines by using [Ru(bpy)3]Cl2 (bpy=2,2′‐bipyridine), CF3I, and 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) (or N,N,N′,N′‐tetramethylethylenediamine, TMEDA) under visible‐light
