Solid State Solution Behavior of Triorganotin (IV) Derivatives Containing the2,4,6-Tris-(Triflu oromethyl)Benzene 1,4-Bis(Perfluoroisopropoxy) Tetrafluorobenzene Ligands: Crystal Molecular Structures of 2,4,6-(CF3)3C6H2Sn(C6H5)3 and 1,4-(CH3)SnOC(CF)32C6F

摘要

The role of sterically and/or electronically demanding ligands in achievingkinetic stabilization of compounds with unusual oxidation/coordination numbers has attracted much attention from main group/transition metal chemists. These sterically demanding groups may be (a) substituted aromatic systems such as the tris(tert-butyl)phenyl (supermesityl), 2,4,6 tris(isopropyl)phenyl, pentamethylcyclopentadiene (Cp*), (b) highly substituted methyl systems, e.g., bis(trimethylsilyl)methyl and tris-(trimethylsilyl)methyl, or (c) bulky imido ligands such as of -Nmesityl(B(mesityl)2), -N(SiMe2Ph)2 and -N(SiMe3)2.
