Arylidene malonate preparation in high yield, for use as intermediate, comprises reacting malonic ester and aromatic aldehyde in presence of ferric chloride as inexpensive, non-toxic catalyst

摘要

The preparation of arylidene malonates or arylidene malonic ester derivatives by reacting malonic esters or their derivatives with aromatic aldehydes is catalyzed by iron (III) chloride (FeCl3).
