“…The activity of the supported zirconium complexes, although improved by the addition of cocatalysts, remained very low by comparison with the homogeneous metallocene systems. This trend has been reported in many works dealing with immobilized metallocenes. 12b,e,14a,15d Several explanations can be considered. It may be that an oxide surface is not a favorable ligand for a polymerization catalyst.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD).
Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD.
The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC).
Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…We are exploring synthetic approaches to metallocene complexes bearing highly electrophilic substituents. , Such species are useful intermediates for the synthesis of ansa -metallocenes 3b-d,5,6 and as precursors to surface-immobilized metallocene catalysts . In earlier reports, we showed that Me 3 Si-substituted group 4 metallocene dichlorides undergo selective, efficient conversion to the corresponding BrMe 2 Si-substituted metallocene dibromides upon treatment with excess BBr 3 . , We now report the results of several reactions of a Me 3 Sn-substituted zirconocene dichloride ( 1 ) with electrophiles (BBr 3 , BCl 3 , I 2 , ICl, and HCl), and we compare the reactivities of the Me 3 Sn and Me 3 Si substituents toward such electrophiles.…”

“…Metallocenes bound to polysiloxanes through the Cp ring were prepared by reacting (H 2 CCH−R−Cp‘) 2 ZrCl 2 complexes (Cp‘ = Cp, Ind) with poly(methylhydrogensiloxane) in the presence of H 2 PtCl 6 ·6H 2 O (Scheme ) ) 18 19 …”
