A broad coverage of boron topics is provided. Structural elucidations and convenient routes to useful hydroboration reagents are presented as well as boron compounds used for medical purposes. Special attention is devoted to theoretical studies and calculations on small boron-hydrogen and boron-noble gas species including molecules like BH, which are rather favorite subjects of theoreticians for testing various methods of calculation.

PF3, (CH3)3SiCl -> (CH3)3SiF, and RC(O)Cl -> RC(O)F. Others include the conversion of (C6H5)3P into (C6H5)3PF2 and of (R3NC(S)S)2 into R2NCF3, R=alkyl. In organic chemistry, fluorides are easily accessible from alcohols, geminal fluorides RR'CF2 from the respective aldehydes or ketones, and acyl fluorides RC(O)F from carboxylic acides by using DAST. Because DAST is easy to handle and gives clean reactions in syntheses, this Gmelin volume devotes much space to the description of the chemical and physical properties od DAST.

"Organoiron Compounds" A, Ferrocene 10 systematicalty covers the literature through the end of 1986 and includes so me references published more recently. A formula index provides ready access to the compounds covered. This volume ends the description of mononuclear unbridged disubstituted ferrocenes, 1 2 FeC HRR . The description of the unbridged disubstituted ferrocenes was initiated with lO a 1 2 "Organoiron Compounds" A, Ferrocene 7 (starting with R and R containing C and Hand 1 containing halogen at least in R and continuing with compounds containing 0 at least in R to form alcohols and...
