    • The regiochemistry of insertion of styrene is shown as having the Ph α to Ti. If the titanacycle had formed with the alternative regiochemistry with Ph β to titanium, the observed stereochemistry of the cyclopropane would also have required retention of configuration at the carbon bonded to titanium.
