✦ Synopsis

Carbon ± carbon bond forming reactions promoted by transition metals are among the basic goals of organometallic chemistry and play an important role in the design of efficient and selective processes. [1] The intramolecular coupling of alkyne and related C 2 ligands (alkynyl, vinyl, vinylidene) is particularly interesting because it constitutes an effective method for the synthesis of useful organic products. [2] The facile migratory insertion of CC units into MÀH and MÀC bonds seems to be decisive not only for these reactions but also for many catalytic processes. [1, 2] Usually bonds between a metal and a perfluorocarbon atom are quite inert towards insertion reactions, and there is currently little or no knowledge on the insertion of acetylene fragments into the robust MÀR F bonds. [3] mimetics combining the biological activity of b-lactams and the countless bioactive properties of conformationally restricted oligopeptides.

Bimetallic complexes play a large role in organometallic chemistry in part because of the potential for cooperative catalytic applications. Of particular interest in this context are hetero-bimetallic systems constructed around a single-carbon (methylene) bridge (sometimes also classified as a "brid
