SYNTHESIS-STUTTGART, v. 47, No. 14, Page. 2038-2054
Optimized procedures to heliphene are described that allowed the synthesis of ((6)-heliphene)tricarbonylchromium and a preliminary exploration of its chemical behavior. DFT calculations provide structural and energetic information on this complex and its haptomeric isomers. Attempts to prepare the corresponding (heliphene)chromium sandwich failed so far, but DFT evidence is presented to indicate that the target should be accessible.
