Applicazioni

Geranyl bromide is used for the preparation of 3,7-dihydroxyflavone derivatives and baicalein. It is also involved in the synthesis of potential flavonoidic modulators of P-glycoprotein activity. Further, it reacts with benzenesulfinic acid to prepare geranyl phenyl sulfone. In addition to this, it takes part in the palladium catalyzed cross coupling with aryl and alkenylgold(I) phosphanes.

Note

Store in a cool place. Incompatible with strong oxidizing agents.
