Tetrakarbonil(4-tert-bütilpiridin)metal(0) Kompleks Bileşiklerinin Sentezi ve Spektroskopik Karakterizasyonu

Year 2020, Volume: 8 Issue: 1, 572 - 577, 31.01.2020

Abstract

Hekzakarbonilmetal(0); M:Cr, Mo, W,
bileşikleri ile sübstitüye piridin (tert-bütilpiridin) arasında,
10 ºC de yapılan fotokimyasal tepkimeler, cis-tetrakarbonil(tert-bütilpiridin)metal(0)
bileşiklerini oluşturmaktadır. Sentezlenen bu organometalik bileşikler yüksek
vakum kullanılarak yeniden kristallendirme yöntemi ile saflaştırılır ve
yapıları FTIR-, 1H- ve 13C-NMR spektroskopileriyle
incelenir. Spektroskopik incelemeler sonucunda elde edilen veriler piridin
ligand halkasının sp2 hibritli azotundan zayıf şekilde bağladığını
ortaya koymaktadır. Ayrıca, piridin halkasının 4-konumu üzerindeki
sübstitüentinin boyutunun, piridin ile merkezi atomun koordinasyonunu
engellemediği gösterilmiştir.

Synthesis and Spectroscopic Analysis of Tetracarbonyl(4-tert-butylpyridine)metal(0) Complexes

Year 2020, Volume: 8 Issue: 1, 572 - 577, 31.01.2020
https://doi.org/10.29130/dubited.597918

Abstract

The photolysis of
hexacarbonylmetal(0); M: Cr, Mo, W, complexes in the presence of a substituted
pyridine ligand  (tert-butylpyridine) at
10 ºC yields the corresponding cis-tetracarbonyl(tert-butylpyridine)metal(0)
complexes. These synthesized organometallic complexes are purified under high
vacuum by recrystallization and their structures are investigated by using IR-,1H-
and 13C-NMR spectroscopies. Spectroscopic investigations reveal that
the pyridine ligand bonded the central atom weakly through the sp2
hybridized nitrogen atom of the ring. In addition to that the size of the
substituent does not hinder the coordination of the pyridine through the central
metal atom.
