The Moment

Aesthetic moments of revelation – intense, sensual, internal, and individual –are so key to modernist culture that the idea of them in criticism has become commonplace. Here I seek to breath life into this humdrum formula of modernist criticism by exploring multiple responses to an alternative moment amongst British cultural figures: the declaration of War against Germany at 11.15 on September 3rd, 1939. This was also an intense moment, but it was social, political, communal, mediated and disseminated publicly by new technologies. As my archival research here reveals, a wide spectrum of responses were recorded, so we can think of such a moment as ‘prismatic’. I will also show how this moment was a shock to culture, which went into a state of suspended animation. As well as offering critiques of the moment as a fetishised form, I argue that modernist culture and the idea of the moment would never be the same again.

 Incorporating selenium metal bonded to the pyridine nucleus was achieved by the reaction of selenium metal with 2-chloropyridine carbonitrile 1 in the presence of sodium borohydride as reducing agent. The resulting non isolated selanyl sodium salt was subjected to react with various α-halogenated carbonyl compounds to afford the selenyl pyridine derivatives 3a-f  which compounds 3a-d underwent Thorpe-Ziegler cyclization to give 1-amino-2-substitutedselenolo[2,3-b]pyridine compounds 4a-d, while the other compounds 3e,f failed to be cyclized. Basic hydrolysis of amino selenolo[2,3-b]pyridine carboxylate 4a followed by decarboxylation furnished the corresponding amino selenolopyridine compound 6 which was used as a versatile precursor for synthesis of other heterocyclic compound 7-16. All the newly synthesized compounds were established by elemental and spectral analysis (IR, 1H NMR) in addition to mass spectra for some of them hoping these compounds afforded high biological activity.
