LE DIHYDROGËNOSULFURE (C5Me5)2Zr(SH)2, SYNTHÈSE ET RÉCTIVITÉ. RÉEXAMEN DES CARACTÉRISTIQUES DE RMN 1H DE SES DÉRIVÉS POLYSULFURÉS

Abstract The thermally stable dihydrogenosulfide (C5Me5)2Zr(SH)2 (1) has been obtained from the corresponding dichloride (2) and hydrogen sulfide in the presence of triethylamine. 1 reacts with sulfur in boiling toluene and with hydrogen sulfide at 80°C affording (C5Me5)2ZrS3. 2 combines to “Li2S” leading to the bimetallasulfane [(C5Me5)2Zr(μ-S)]2. A mixture of (C5Me5)2Zr(OH)(SH) and dihydroxyde was formed by the reaction of water on the dihydrogenosulfide. The 1H NMR chemical schifts of the compounds are discussed.
