                                摘要:
                                A multistep route for obtaining the polynucleating open-chain systems 3-5 is reported. These advanced intermediates required elaborate processes that proceeded for the pentanuclear proto-phanes 3 in seven steps, whereas the trinuclear compounds 4 and 5 were obtained in six steps.
