Photolytic induction of the asymmetric catalytic complexation of prochiral cyclohexa-1,3-dienes by the tricarbonyliron fragment using a camphor-derived azadiene catalyst provides the corresponding tricarbonyliron complexes quantitatively in up to 86% ee.

Heating of allylic amide or allylic ester substituted diene–Fe(CO)3complexes such as (7) and (10)(140 °C) results in an intramolecular coupling of the pendant double bond with the diene moiety to give spirolactam and spirolactone derivatives; the stereochemical course of this reaction was established by an X-ray crystal structure determination of the lactone derivative (11).

Intramolecular double cyclization between a cyclohexadiene-Fe(CO)3 complex and a pendantdiene yielded a tricyclic molecule containing a spirocenter, with defined relative stereochemistry of four contiguous carbon centers. The nature of the substituent on the pendantdiene moiety has a significant effect on the yield: an ester group leads to lower yield. The product has a conjugated cyclohexadiene

l)iron hexafluorophosphate proceeds in a regioselective manner using either zinc dust or electrochemical techniques, cyclic voltammetry experiments providing evidence for a one-electron transfer process involving freeradical intermediates; the first example of intramolecular crosscoupling of the freeradical with an alkene moiety is reported.
