“…The required 1‐benzyl‐2‐chloro‐1,2‐diduryldiborane(4) 1 was prepared by the surprisingly selective reaction of 1,2‐dichloro‐1,2‐diduryldiborane(4) [21] with one equivalent of benzyl magnesium chloride [22] at −78 °C in 97 % yield. It was characterized by multinuclear NMR spectroscopy and single crystal x‐ray diffraction (see Supporting Info).…”

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.

“…12,22 The precursors 3-Ar are obtained via a three-step procedure by (a) arylation of B 2 X 2 (NMe 2 ) 2 (X = Cl, Br) with LiAr to yield 1-Ar , followed by (b) acidic methanol quenching to yield 2-Ar , and finally (c) bromination to yield 3-Ar (Scheme 1). 25–27 Attempts to synthesise the corresponding diphenanthryl- and dipyrenyldiboranes(4) following the same procedure failed as step (b) was systematically followed by B–B bond cleavage of 2-Ar during workup. Although 2-Ar was detected in the 11 B NMR spectrum of the reaction mixture at ca.…”

“…Das benötigte 1‐Benzyl‐2‐chlor‐1,2‐diduryldiboran(4) 1 wurde durch die überraschend selektive Reaktion von 1,2‐Dichlor‐1,2‐diduryldiboran(4) [21] mit einem Äquivalent Benzylmagnesiumchlorid [22] bei −78 °C in 97 % Ausbeute erhalten. Es wurde mithilfe von multinuklearen NMR‐Experimenten und Röntgenbeugung am Einkristall analysiert (siehe Hintergrundinformationen).…”
