A series of five new syn ‐bidentate ligands 14−18 based on the [1.1.1.1]metacyclophane backbone blocked in a 1,3‐alternate conformation was achieved. The common building block for the preparation of ligands bearing two interaction sites located in a syn fashion (CN, SMe, p ‐pyridyl, p ‐methoxyphenyl and p ‐methylthiophenyl) is the dibromo derivative 12 . All reported ligands were fully characterised by classical analytical methods and their 1,3‐alternate conformation demonstrated. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
