Title (EN) SYNTHETIC METHODS PERTAINING TO TERT-BUTYL-BENZENE-BASED COMPOUNDS
(FR) PROCÉDÉS DE SYNTHÈSE CONCERNANT DES COMPOSÉS À BASE DE TERT-BUTYL-BENZÈNE
Abstract: front page image
(EN)According to some aspects, the present disclosure pertains to methods of forming dimethyl 5-tert-butylisophthalate which comprise comprising converting 5-tert-butylisophthalic acid into dimethyl 5-tert-butylisophthalate in synthesis procedures that comprises methanol and a dehydrating agent as chemical reagents. In other aspects, the present disclosure pertains to methods of forming 5-tert-butyl-1,3-bis(1-methoxy-l-methylethyl) benzene that comprise deprotonating 5-tert-butyl-1,3-bis(1-hydroxy-l-methylethyl)benzene with a Brønsted-Lowry superbase and methylating the deprotonated 5-tert-butyl-1,3-bis(1-hydroxy-l-methylethyl)benzene to form the 5-tert-butyl-1,3-bis(1-methoxy-l-methylethyl)benzene.
(FR)La présente invention concerne dans certains aspects des procédés de formation diméthyl 5-tert-butylisophtalate consistant à transformer de l'acide 5-tert-butylisophtalique en diméthyl 5-tert-butylisophtalate dans des procédures de synthèse qui comprennent du méthanol et un agent déshydratant comme réactifs chimiques. Dans d'autres aspects, la présente invention concerne des procédés de formation de 5-tert-butyl-1,3-bis(1-méthoxy-l-méthyléthyl)benzène qui consistent à déprotoner du 5-tert-butyl-1,3-bis(1-hydroxy-l-méthyléthyl)benzène avec une superbase de Brønsted-Lowry et méthyler le 5-tert-butyl-1,3-bis(1-hydroxy-l-méthyléthyl)benzène déprotoné pour former le 5-tert-butyl-1,3-bis(1-méthoxy-l-méthyléthyl)benzène.
