Diethyl oxalate was used in microemulsion synthesis of ZnO nanoparticles1. It was also used in the synthesis of sym-1,4-diphenyl-1,4-dihydro-1,2,4,5-polytetrazine2.

General description

Diethyl oxalate undergoes transesterification with phenol in the liquid phase over very efficient MoO3/TiO2 solid-acid sol-gel catalysts to form diphenyl oxalate3. It undergoes Claisen condensation with active methylene group of ketosteroids to form glyoxalyl derivatives4. It undergoes hydrogenation in the presence of high copper contented mesoporous Cu/SBA-15 catalysts to yield ethylene glycol5.
