Crystal structure of 3-ferrocenyl-1-phenyl-1H-pyrrole, [Fe(η5-C5H4cC4H3NPh)(η5-C5H5)]Pfaff, Ulrike, Korb, Marcus, Lang, Heinrich 13 May 2016 (has links) (PDF)
The molecular structure of the title compound, [Fe(C 5 H 5 )(C 15 H 12 N)], consists of a ferrocene moiety with an N-phenylpyrrole heterocycle bound to one cyclopentadienyl ring. The 1,3-disubstitution of the pyrrole results in an L- shaped arrangement of the molecule with plane intersections of 2.78 (17)° between the pyrrole and the N-bonded phenyl ring and of 8.17 (18)° between the pyrrole and the cyclopentadienyl ring. In the crystal, no remarkable intermolecular interactions are observed.

Sinteza i biološka aktivnost novih steroidnih heterocikličnih jedinjenja / Synthesis and biological activity of new steroidal heterocyclic compoundsOklješa Aleksandar 24 July 2015 (has links)
<p>U ovoj doktorskoj disertaciji ispitane su 1,3-dipolarne<br />cikloadicione reakcije steroidnih azido-nitrila, nitrona i<br />nitril-oksida, pri čemu su sintetizovana različita<br />heterociklična steroidna jedinjenja androstanske i estranske<br />serije. Utvrdjene su strukture novosintetizovanih<br />jedinjenja. Ispitana je biološka aktivnost odabranih<br />jedinjenja.</p> / <p>In this PhD thesis 1,3-dipolar cycloadditions of<br />steroidal azido-nitriles, nitrones and nitrile-oxide were<br />examined. Various steroidal heterocyclic compounds in<br />the androstane and estrane series were synthesised. The<br />structural characterisation of newly synthesised<br />compounds was done. Biological activity of selected<br />compounds was examined.</p>
