KINETIC STUDIES OF THE SYSTEM TUNGSTEN HEXACHLORIDE/TETRAMETHYLTIN (DIETHYL ETHER)/C5-OLEFINS; DETERMINATION OF THE INITIAL REACTION STEPS.

The initial steps in the catalyst system tungsten hexachloride/tetramethyltin/C//5-olefins have been studied kinetically. UV-vis spectroscopic examinations have shown that the first alkylation step proceeds as a second-order reaction with the low activation energy of 26. 1 kJ mol** minus **1. The reaction between tungsten hexachloride and C//5-olefins leads quantitatively to tungsten pentachloride which is formed as a stable intermediate compound. This reaction, which is much slower than the alkylation step, is of great importance in the presence of high olefin concentrations, and especially in the case of cyclic olefins.

New route to the preparation of tungsten pentachloride

Studies of the reaction between tungsten hexachloride and olefin show that the reduction of tungsten hexachloride with olefins is applicable to the preparation of tungsten pentachloride.

The Use of (Me3Si)2NN(SiMe3)2 as a Reagent for the Synthesis of μ-Dinitrogen Complexes or as a Homogeneous One-electron Reducing Agent

The reaction of NbCl5 with (Me3Si)2NN(SiMe3)2, in the presence of tetrahydrofuran (thf) gives high yields (ca. 80percent) of 2N2> (A); (A), or its tantalum analogue, reacts with Me3SiS2CNEt2 to give a high yield of the dinitrogen complexes with exclusively sulphur co-ligands 2N2> (M = Nb or Ta), and reaction of (L = MeCN or thf) with (Me3Si)2NN(SiMe3)2 gives in high yield, together with N2.

Kinetic study of Hubnerite (MnWO4) chlorination

The kinetics of Argentinean Hubnerite (MnWO4) chlorination using gaseous chlorine as chlorination agent was studied between 750 and 950 °C. The relative mass change during the chlorination reaction was continuously monitored using a high resolution thermogravimetric system. The starting temperature for the reaction of the manganese tungstate with chlorine was determined at about 650°C. The influence of gaseous flow rate, sample mass, chlorine partial pressure, and temperature on the reaction rate was analyzed. The dependence of the reaction rate with sample mass clearly indicates that the reaction is not occurring under chemical control, so the reaction proceeds under mixed control for sample masses greater than 0.5 mg. In those conditions, an apparent activation energy of 198 ± 9 kJ mol-1 was obtained with an isoconversional method. Concerning the influence of chlorine partial pressure, it was determined that pressures greater than 35 kPa do not modify the kinetic regime. For the experiment at 850°C, it was found that the chlorination rate was proportional to a potential function of the partial pressure of chlorine whose exponent is around 0.85. Finally, a global rate equation that includes these parameters was developed.

Spectroscopic Studies on Matrix Isolated Tungsten Chlorides and Bromides

Tungsten pentachloride has been heated in high vacuum, and the vapour species isolated in inert matrices at ca. 12 K.Subsequent i.r. spectra showed intense features at 410 and 365 cm-1 which are assigned as the A2'' and E' stretching modes respectively of monomeric D3hWCl5.Corresponding studies on the hexachloride showed that monomeric WCl6 could similarly be isolated, and for this species, the u.v.-visible spectrum was also obtained and analysed in detail.The vaporisation of tungsten bromide samples of typical stoicheiometry WBr5.3 yielded a new spectroscopic feature in the matrix i.r. spectrum at ca. 305 cm-1 which is assigned to molecular WBr6.At higher temperatures, the vaporisation of the solid pentabromide resulted in bands at 280 and 245 cm-1 which are assigned as the A2'' and E' stretching modes in D3hWBr5.
