Carboxylic acid production of tertiary butyl

PROBLEM TO BE SOLVED: To provide a process for producing a carboxylic acid tert-butyl ester industrially advantageously.SOLUTION: The process for producing a carboxylic acid tert-butyl ester includes reacting compounds represented by formula (1) and formula (2) (wherein Y denotes a 1-20C alkoxy group) with isobutene in the presence of an acid catalyst and at normal pressure by using a mixed solvent containing an aromatic hydrocarbon.

Mild and efficient method for preparation of tert-butyl esters

Aliphatic and aromatic methyl esters undergo efficient transesterification at ambient temperature with potassium tert-butoxide in diethyl ether.

A New Acylation Catalyst

Cobalt(II) chloride catalyses the acylation of alcohols and amines with anhydrides in excellent yields.

Alkynes and Cumulenes, XII. The Application of Di-tert-butyl Acetylenedicarboxylate in Diels-Alder Additions

Di-tert-butyl acetylenedicarboxylate (1) may be added in good yields to the model dienes 1,3-butadiene (6a), 2-methyl-1,3-butadiene (6b), 2,3-dimethyl-1,3-butadiene (6c), furan (10), and 1,3-cyclohexadiene (19) to afford the Diels-Alder adducts 7a-c, 12 (E = CO2C(CH3)3), and 20, respectively.Under certain conditions the reaction with 10 also laeds to the four 2:1-adducts 13-16 (E = CO2C(CH3)3).Whereas the esters 7a-c are converted in quantitative yields to the corresponding anhydrides 8a-c by warming in the presence of catalytic amounts of p-toluenesulfonic acid or by heating in substance, the decomposition of 12 and 20 stops at the stage of the monoesters 17 and 21, respectively.Competition experiments show that 1 is approximately three times less reactive towards 6c than dimethyl acetylenedicarboxylate (11).It is shown that 1 is a useful dienophile for the preparation of "mixed" paracyclophanes of type 28.
