Beschreibung

Allgemeine Beschreibung

Diallyl carbonate is an acrylating agent. Allyl carbonates are widely employed in Tsuji-Trost allylation, generating carbanion, boronate, phosphide, amide and alkoxide, nucleophiles in situ and improving reaction rates over allyl acetate. Allyl carbonates are also of considerable interest for the intramolecular decarboxylative assymetric couplings.

Anwendung

Transesterification of diallyl carbonate with glycerol in the presence of a catalyst (Pd/PPh₃), generates glycerol carbonate.
