Main Group Compounds

Abstract

Chapter 1, “Main Group Compounds and Ligands,” is a collection of syntheses that focus primarily on the main group elements. These include a number of compounds of boron and aluminum, e.g., the diboron compound B2(1,2-O2C6H4)2, the sodium salt of a non-coordinating anion, Na[B(3,5-(CF3)2C6H2)4], salts of a potentially tridentate “scorpionate” ligand, e.g., [n-Bu4N][PhB(CH2PPh2)3], cationic six-coordinate aluminum complexes, such as [Al(Salen)(H2O)2]Cl, and a tabular form of α-alumina. In addition there are syntheses of useful carbon and nitrogen ligands, such as para-substituted aryl isocyanides, e.g., p-CNC6H4NC, and unsymmetrical tripod ligands with mixed pyridyl and pyrazolyl appendages. Also included are detailed procedures for the preparation of tetramethylammonium salts of superoxide and peroxynitrite, the pentavalent arsenic compound, AsF2Ph3, and several tellurium-nitrogen compounds derived from lithium tert-butylamide, Li[HNtBu].
