FACILE AND HIGHLY SELECTIVE SYNTHESIS OF 2,2-DIALKYL-1,5-LACTONES BY THE CALBOXYLATION OF PRIMARY, TERTIARY-1,4-DIOLS WITH FORMIC ACID OR COPPER(I)CARBONYLS IN THE PRESENCE OF CONCENTRATED SULFURIC ACID

The carboxylation of primary, tertiary-1,4-diols with 100% formicacid or copper(I)carbonyls and carbonmonoxide in the presence of 97∼100% H2SO4 at room temperature and under atmospheric pressure gave 2,2-dialkyl substituted 1,5-lactones in high yields.
