Abstract
Abstract Recent developments in the understanding of some fundamental reactions undergone by group 10 metal allyl and propargyl (2-propynyl) complexes are described. Emphasis was placed on the bonding-reactivity relationship of these complexes which are relevant as key intermediate models in transition metal catalyzed transformations of allylic and propargylic substrates as well as related transformations involving unsaturated hydrocarbons. The specific complexes surveyed include group 10 metal complexes of allyl and propargyl ligands bound to the metal both in η1- and η3-fashions. Specific reactions to be discussed include oxidative addition, nucleophilic and electrophilic attack at the allyl or propargyl ligands, and reductive elimination of the allyl ligands.
