Aryl ketones react readily with oxatitanacyclobutenes bearing pentamethylcyclopentadienyl ligands to form unique titanocene complexes resulting from Cp* modification and C–H activation. An intermediate in this reaction is intercepted with various functional groups to form carbonyl insertion, C–F activation, and cyclopropane ring-opening products.
