Web2 days ago · A step in a synthesis of PGE1 (prostaglandin E1, alprostadil) is the reaction of a trisubstituted cyclohexene with bromine to form a bromolactone. Propose a mechanism for formation of this bromolactone and account for the observed stereochemistry of each substituent on the cyclohexane ring. WebThe second experiment to identify cyclohexane from cyclohexene is using the bromine reaction. Bromine is a strong electrophile and has a characteristic red-brown color. These properties make bromine a useful reagent for probing the reactivity of colorless nucleophilic organic compounds such as alkenes.

WebJan 28, 2024 · The bromine atom in the bromonium ion acts as a shield in a way, forcing the bromonium anion to attack from the opposite side as it. The result of this is the ring opening up with the two halogens on opposite sides as each other. This is anti stereochemistry, which is defined as the two bromine atoms come from opposite faces of the double bond.
