DESCRIPTION
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 oxalate[1]. It undergoes Claisen condensation with active methylene group of ketosteroids to form glyoxalyl derivatives[2]. It undergoes hydrogenation in the presence of high copper contented mesoporous Cu/SBA-15 catalysts to yield ethylene glycol[3].
Application
Diethyl oxalate was used in microemulsion synthesis of ZnO nanoparticles[4]. It was also used in the synthesis of sym-1,4-diphenyl-1,4-dihydro-1,2,4,5-polytetrazine[5]. |
