“…In general, structures of fulvene complexes can be described on the basis of two resonance forms ( I and II ). Because of the resonance form II , in which the exo carbon has a partial positive character and the Cp fragment has an aromatic character, the exocyclic double bond is susceptible to nucleophilic addition. − In our reactions, the solvent alcohol (probably in the form of an alkoxide) appears to have undergone nucleophilic attack at the exo carbon of a fulvene intermediate (the resonance form II ) to give a substituted Cp ring. …”
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.

“…The bridging Mg−C distances are similar to those in [(C 5 Me 4 Et)Mg(μ-Me)THF] 2 . 19 This structure is distinguished from the monomeric structures obtained with κ 2 -η 5 -{HC(Pz Me2 ) 2 (Ph 2 CC 5 H 4 )}MgR (Pz Me2 = 3,5-dimethylpyrazolyl; R = CH 2 SiMe 3 , t Bu), 20 although a number of cyclopentadienyl magnesium piano-stool compounds have been crystallographically characterized to contain monohapto to pentahapto coordination modes, including (η 1 -C 5 H 5 )(η 5 -C 5 H 5 )MgTHF 2 . 21 Notably, the solid-state IR spectrum of amorphous material suggests equivalent oxazolines.…”

“…The magnesium–carbon distances of the bridging methyl groups are similar but unequal (Mg1–C22, 2.267(2) and Mg1–C22#, 2.271(2) Å) and similar to the shortest distance in the magnesium-cyclopentadienyl interaction. The bridging Mg–C distances are similar to those in [(C 5 Me 4 Et)Mg(μ-Me)THF] 2 . This structure is distinguished from the monomeric structures obtained with κ 2 -η 5 -{HC(Pz Me2 ) 2 (Ph 2 CC 5 H 4 )}MgR (Pz Me2 = 3,5-dimethylpyrazolyl; R = CH 2 SiMe 3 , t Bu), although a number of cyclopentadienyl magnesium piano-stool compounds have been crystallographically characterized to contain monohapto to pentahapto coordination modes, including (η 1 -C 5 H 5 )(η 5 -C 5 H 5 )MgTHF 2 …”

“…substituted bis(cyclopentadienyl)magnesium complexes, are a well‐established and intensely studied substance class of broad interest [22] . Most commonly, cyclopentadienes have been metalated with Mg‐based organometallics; an alternative is the addition of such reagents onto fulvenes [23] . The magnesium ions are effectively shielded by two parallel cyclopentadienide ligands leading to thermodynamically and kinetically stabilized compounds.…”

[23] The magnesium ions are effectively shielded by two parallel cyclopentadienide ligands leading to thermodynamically and kinetically stabilized compounds. In heteroleptic (substituted) cyclopentadienylmagnesium halides the Mg atoms are accessible for substrate molecules allowing transformations at the alkaline-earth metal atom.…”
