Preparation and Study of the Structure of some Inorganic Complexes
Ghada Mohamed Nazir Bassioni;
Abstract
The inorganic complexes prepared and studied in this thesis represent two types of organometallic compounds.
1. Reaction of a bicyclic ether with trimethyltin chloride
The wide application of tin compounds in technology and in synthesis has lead to an intensive research. Tin organyls are used as PVC-stabilizers and biocides. Besides tin has a special role in structure analysis via 119Sn NMR spectroscopy.
Trimethyltin chloride can react with anions of organic ligands to give the corresponding trimethyltin derivatives, a process called metallation. A number of metallation reactions have been reported on various systems. The formation of cyclopentadienyl-like ligands has been subject to intensive investigation. In this work the preparation of endo,endo-9-
oxabicyclo[3.3.J]nona-2,6-diene and the formation of its anion, which is
•
then trapped by trimethyltin chloride has been discussed. Two
trimethyltin derivatives could be investigated, the endo- and the exo- 4- trimethyltin-9-oxabicyclo[3.3.l]nona-2,6-diene.
2.Reaction of isatin with some metalcarbonyls
The coordination chemistry of quinones has developed dramatically over the past 25 years. Scattered accounts of transition metal complexes containing quinone ligands in their various electronic forms have appeared. With the characterization on quinone complexes of the Cr, Mo and W triad differences appeared between the quinone coordination chemistry of the first raw metal relative to the larger metals of the group. Their wide application made a study on the very similar isatin (indole-
2,3-dione) of interest.
Two chromium complexes were isolated from the reaction of chromium hexacarbonyl, Cr(C0)6 with isatin in THF.
