Title (EN) PROCESSES FOR SYNTHESIZING 1-(2-ETHYLBUTYL) CYCLOHEXANE CARBONITRILE
(FR) PROCÉDÉS DE SYNTHÈSE DE 1-(2-ÉTHYLBUTYL)CYCLOHEXANE CARBONITRILE
Abstract: front page image
(EN)Processes are provided for synthesizing substituted cyclohexane carbonitriles, particularly 1-(2-ethylbutyI)cyclohexane carbonitrile. Such processes comprise deprotonizing cyclohexane carbonitrile with chloro magnesium N,N-diisopropylamide and alkylating the deprotonated cyclohexane carbonitrile in the presence of 2-(ethylbutyl) bromide to produce 1-(2-ethylbutyl)cyclohexane carbonitrile.
