Di- and Polynuclear Compounds 5

Book excerpt: The present volume is the fifth and for the present moment last in a series of volumes on organotitanium compounds. It covers the literature to the end of 1987. The volume continues the treatment of titanium compounds with the dinuclear and polynuclear complexes. The main part of this volume deals with the dinuclear complexes and therein (+-C5H5)2TiCl 2 is the most frequently described compound. Another key compound in this volume is the presumably oligomeric +-C5H5TiCl2 n. This volume also deals with different "titanocenes" de- scribed in the literature. There are also well-defined tri- and tetranuclear compounds, one penta- and a few hexanuclear compounds. "Black titanocene" is described together with the oligonuclear compounds. Polymers containing (+-C5H5)2TiIV units conclude this volume. As in the preceding volumes of this series, compounds of debatable existence and postulated reaction intermediates are included for completeness. A Formula Index and a Ligand Formula Index for this volume are included.
