General description

Iodine monobromide is an interhalogen compound used as an electrophile in the synthesis of polyketide structural units.

Iodine monobromide (IBr) is a powerful iodinating agent employed in organic synthesis. IBr is commonly used in cleavage of carbon–metal bonds, electrophilic addition to alkenes, α-bromination of steroidal ketones and aldehydes, and in diastereoselective cyclizations of homoallylic carbonates.

Application

Electrophile employed in a new synthetic approach to polyketide structural units.
