Multifold Ring‐Closing Olefin Metatheses in Syntheses of Organometallic Molecules with Unusual Connectivities Chapter uri icon


  • © 2014 John Wiley & Sons, Inc. In 2003, one of the authors of this chapter noted that using a transition metal catalyst to carry out a reaction on a transition-metal-containing substrate might at first seem to be a risky proposition. In this regard, it is now well established that olefin metatheses can be carried out in diverse types of metal coordination spheres. This chapter focuses on a more challenging subset of processes, namely, those involving multifold ring-closing metatheses and the generation of organometallic molecules with unusual connectivities. Transformations that may involve multiple olefin metatheses but do not yield multiple cycles-for example, ring-opening metathesis polymerizations-are excluded. The chapter illustrates the various types of multifold ring-closing metatheses in a logical order, as opposed to exhaustively cataloging them. One approach to probing kinetic versus thermodynamic control in many of the above schemes would involve separation of the two types of metathesis products prior to the customary hydrogenation.
