Product details

cyclic-isopropylidene malonate

Xinxiang Hongqi District Houyuan Trading Co.,ltd has 7 years of experience in producing cyclic-isopropylidene malonate.

Through condensation of hydroxyl aldehyde and reduction with triethylamine formaldehyde, benzyl substituted Meldrum's acid was hydrolyzed, CO2 and chlorosulfonic acid were lost to Friedel-Crafts cyclization to form 2o 3-dihydro-2-indenone. The Knoevenagel condensation reaction between aldehyde and Meldrum's acid was accelerated in ionic liquids.
