Cerium(IV)-promoted ethylation of Schiff bases by triethylaluminum
Tsvelikhovsky, Dmitry,Schumann, Herbert,Blum, Jochanan
, p. 1819 - 1822 (2006)
Schiff bases Ar1CH=NAr2 that are refractory towards Et3Al are activated at room temperature by cerium(IV) compounds. The ethylation takes place selectively at the methine moiety of the imine. The process is strongly influe

Equation presented. Schiff bases of aromatic aldehydes and anilines that fail to react with triethylaluminum are smoothly alkylated at room temperature in the presence of lanthanide catalysts. The alkylation takes place selectively at the vinylic carbon a
Diethylzinc: A chain-transfer agent in intermolecular radical additions. A parallel with triethylborane

In the presence of oxygen, diethylzinc can be used to promote radical additions to C=N bond containing radical acceptors and to enones. In these reactions, it plays at the same time the role of the initiator and the role of the chain-transfer reagent. A p
