Reduction of [(η5-CH3C6H6)Fe(CO)3]+PF6− by NaBH4, LiBH4, LiEt3BH and KBu53BH becomes less regioselective at lower temperatures. Regioselectivity of reduction by 9-BBN, however, improves as the temperature is lowered. Factors affecting nucleophilic addition are discussed in terms of likely transition states for the competing processes.
