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-1-methylethyl)benzene that comprise deprotonating 5-tert-butyl-1,3-bis(1-hydroxy-1-methylethyl)benzene with a Brønsted-Lowry superbase and methylating the deprotonated 5-tert-butyl-1,3-bis(1-hydroxy-1-methylethyl)benzene to form the 5-tert-butyl-1,3-bis(1-methoxy-1-methylethyl)benzene.
根据某些方面,本公开涉及形成二甲基5-叔丁基异苯二甲酸酯的方法,包括将5-叔丁基异苯二甲酸转化为二甲基5-叔丁基异苯二甲酸酯,在合成过程中使用甲醇和脱水剂作为化学试剂。在其他方面,本公开涉及形成5-叔丁基-1,3-双(1-甲氧基-1-甲基乙基)苯的方法,包括用布朗斯特-洛瑞超碱去质子化5-叔丁基-1,3-双(1-羟基-1-甲基乙基)苯,并甲基化去质子化的5-叔丁基-1,3-双(1-羟基-1-甲基乙基)苯以形成5-叔丁基-1,3-双(1-甲氧基-1-甲基乙基)苯。
