In the old days of leaded gasoline, halogen compounds were added as lead scavengers. But since leaded gasoline has been banned, modern fuels don't have those compounds present anymore. They may have some amines but those are going to oxidize to NOX compounds in low concentrations. The unburned gasoline (along with methanol) is going to far more toxic than any combustion products would be.
