Zinc Perchlorate Hexahydrate Catalyzed Mono- and Bis-Transesterification of Malonic Esters
Transesterification zinc perchlorate malonic esters mono-substituted malonic esters unsymmetrical malonic esters
2010/4/16
Commercially available zinc perchlorate hexahydrate [Zn(ClO4)2.6H2O] was found to be a highly effective catalyst for the transesterification of malonic esters with alcohols. The treatment of methyl-, ...
