Anwendungen

Dibenzyl malonate is used in the preparation of tetraethyl 3,3-bis(benzyloxycarbonyl)propylene bisphosphonate. It was also used in the preparation of benzyl umbelliferone-3-carboxylate via Knoevenagel condensation with 2,4-dihydroxybezaldehyde. It is a useful alternative to Diethyl­ malonate.

Bemerkungen

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Incompatible with oxidizing agents.
