A convenient and sustainable method for the synthesis of glycol diesters was developed through the depolymerization of polyethylene glycols (PEGs) with carboxylic acids using proton-exchanged montmorillonite as an efficient solid acid catalyst. Several functionalized glycol diesters were obtained in good yields from PEGs and readily available carboxylic acids. Upon reaction completion, the catalyst could be easily separated by filtration and reused with its activity remaining unchanged.

A simple and efficient DDQ-mediated oxidative C-O coupling reaction between acetalic sp3 C-H and carboxylic acid O-H bonds has been developed. This novel transformation smoothly proceeds without any metal catalyst and allows for the highly efficient synthesis of (un)symmetric glycol diesters in a single step. This journal is
SUBSTITUENT EFFECTS ON THE DECOMPOSITION OF 1,2-DIOXETANES: A HAMMETT CORRELATION FOR SUBSTITUTED 1,6-DIARYL-1,5,7,8-TETRAOXABICYCLOY4.2.0(OCTANES

Rates of decomposition for 1,2-dioxetanes obtained from addition of singlet oxygen to substituted 2,3-diaryl-1,4-dioxenes have been found to obey a Hammett relationship with ?=++-0.24 (n 15, r 0.92).The results are taken as support for a biradical mechanism.
