Abstract: front page image
(EN)A process for the preparation of arylcyclobutylnitrile derivatives which involves reaction of a solution of a 1,3-dihalopropane and a cyanobenzyl derivative in a substantially dimethyl sulphoxide-free solvent with a suspension of a base in a substantially dimethyl sulphoxide-free solvent at a temperature of at least 35 °C.
(FR)Ce procédé de préparation de dérivés d'arylcyclobutylnitrile consiste à faire réagir une solution de 1,3-dihalopropane et d'un dérivé de cyanobenzyle dans un solvant sensiblement dépourvu d'oxyde sulfonique de diméthyle, avec une suspension d'une base dans un solvant sensiblement dépourvu d'oxyde sulfonique de diméthyle, à une température d'au moins 35 °C.
