The unique molecular discriminations are observed in the Eu(III)-catalyzed reactions of saturated ketones, α,β-enones, and α,β-ynones with ketene silyl acetals and discussed in terms of the discriminating ability of the Eu-catalyst at the complexation sta

A process for the preparation of hydroxy and amino compounds, in which, in a first step, an aldehyde, ketone or imine is reacted in a Reformatsky reaction with a reactive halogen compound and zinc, in carboxylic esters as solvents, the reactive halogen compound being brought into contact with the zinc at the same time as or after contact with the aldehyde, ketone or imine, and in a second step, the reaction product of the first step is hydrolyzed.

The mechanism of the electroreductive coupling of α-chloro esters or α-chloro nitriles with carbonyl compounds by the means of a sacrificial zinc anode and a nickel catalyst was elucidated by electroanalytical techniques.The mechanism involved reduction of a Ni(II) complex to a Ni(0) complex, oxidative addition of the α-chloro ester to the Ni(0) complex, and a Zn(II)/Ni(II) exchange, leading to an organozinc Reformatsky reagent.The electrosynthesis of various β-hydroxy esters, β-hydroxy nitriles, and 2,3-epoxy esters was successfully achieved under extremely mild conditions.
