Preface

The present VoLume 4 of "Boron Compounds" 3rd SuppLement concLudes the 3rd suppLement issue on boron compounds, but will be augmented by a separate index voLume for the boron compounds discussed in the four voLumes of this specific suppLement. This 3rd suppLement adds on to the previous voLumes dealing with boron compounds beginning (in parentheses: Literature cLosing dates) with the Main VoLume (end of 1925), SuppLement VoLume 1 (end of 1949), SuppLement VoLume 2 (end of 1975 for boron carbides, mid-1980 for eLementaL boron), "Boron Compounds" VoLumes 1 to 20 and FormuLa Index, "Boron Compounds" 1st SuppLement (3 voLumes, end of 1977), and "Boron Compounds" 2nd SuppLement (2 voLumes, through 1980). In the 3rd suppLement the Literature is covered uniformLy through 1984.

The present voLume contains the description of boron compounds with CL, Br, and I, as weLL as the systems of boron with S, Se, Te, and Po. The finaL chapter describes the carboranes; it contains the description of carboranes as weLL as brief discussions of metaLLacarboranes and a Listing of carborane-containing poLymers.

The IUPAC nomencLature is mostly adhered to; occasionaL abbreviations for compounds are expLained in the text. UnLess otherwise noted, a positive sign for the chemical shifts on the NMR signaLs indicates downfieLd from the references: (CH3)4Si for [)'H and [)'3C, (C2H5hO-BF3 for [)"B, aqueous NaN03 for [)'4N, and CFCL3 for [)'9F.
