Protonolysis, deuterolysis, and halogenolysis of five-membered zirconacycles proceed in a similar manner to the corresponding reactions with bis(η5-cyclopentadienyl)monoorganozirconium(IV) complexes (Section ‌2.11.4.6‌). The two reactive Zr—C bonds of the zirconacycles can selectively react with protonating, e.g. hydrogen chloride or methanol, and halogenating agents, e.g. iodine or N-bromosuccinimide, either in two discrete stages or concurrently under one set of reaction conditions (‌Scheme 92‌). The Zr—Cp bonds generally remain unreacted.
