describes the chemo- and stereoselective benzylic C(sp3)–H alkenylation of tertiary ortho-methyl anilines with internal alkynes using a simple β-diketiminato scandium catalyst. This protocol offers an efficient method for the synthesis of a new family of tertiary ortho-allylanilines in high yields. The resultant alkenylation products facilely underwent further chemical transformation to other valuable anilines

[EN] Benzene derivatives having optionally substituted amino or morpholino in the 1 and 4 position, optionally alkyl in the 2, 3 and 6 position and optionally alkyl or nitro in the 5 position or wherein the 1 and 6 substituents together form a heterocyclic ring, can be used as a charge transfer mediator in a biochemical process involving electron transfer between a redox system and an electrode comprising a paste of electrically conductive particles and a pasting material. [FR] On peut utiliser des dérivés benzéniques possédant un amino ou morpholino facultativement substitué en position 1 et 4, éventuellement un alcoyle en position 2,3, et 6 et éventuellement un alcoyle ou un nitro en position 5 ou dans lesquels les substituants 1 et 6 forment ensemble un noyau hétérocyclique comme médiateur de transfert de charge dans un procédé biochimique comportant le transfert d'électrons entre un système de redox et une électrode comprenant une pâte de particules électriquement conductrices et un matériau d'empâtage.

An efficient and selective benzylic C(sp3)–H addition of o-CH3-substituted tertiary aromatic amines to alkenes has been achieved using an anilido-oxazoline ligand supported scandium catalyst, which provides an atom-economic method for the synthesis of a new family of alkylated tertiary anilines. A wide range of amine and alkene substrates are compatible with the catalyst system.
