(2016) Complexes of Iron(II) with silylated pentalene ligands; building blocks for homo-and heterobimetallics.

DFT calculations on model mono-Fe(η 5 -Pn) compounds reveal the charge densities on the uncoordinated carbon atoms of the pentalene ligand, and hence the potential for incorporating these units into heteronuclear bimetallic complexes is assessed.

Iron(II) High‐Spin and Low‐Spin Complexes from Pentaisopropylcyclopentadienyliron(II) Bis(trimethylsilyl)amide

“…The absence of strongly bound π‐acceptor ligands like carbon monoxide, the removal of which often requires photochemical or thermal activation, is an advantage especially in combination with enough thermal stability for convenient storage in the laboratory. Complex 1 was used for the synthesis of pentamethylcyclopentadienyliron(II) half‐sandwich or sandwich complexes with olefin ligands, indenyl ligands, functionalized pyrrolide rings for use as pincer ligands, pentalene ligands for use as building blocks, phospholyl ligands, naphthalene, or anthracene bridges between two Cp*Fe moieties, or bridging thiolate ligands for the stoichiometric and catalytic reduction of methylhydrazine . Complex 1 has also been used for a facile one‐pot synthesis of an iron(III) half‐sandwich catalyst precursor with a tridentate phosphinebis(thiolate) ligand using air for oxidation or for the one‐pot synthesis of the ferrate(0) [(tmeda)Li(µ‐C 2 H 4 ) 2 FeCp*] with lithium sand and ethylene , …”

“Modern Day Trojan Horse?” Analyzing the Nexus between Islamophobia and Anti-Refugee Sentiment in the United States

“…The Islamophobia industry has co-opted the word "hijra" to describe a "slow-motion conquest by migration." 35 In Arabic, the word hijra literally means "migration" or "emigration." For Muslims, hijra refers to the Prophet Mohammed's journey from Mecca to Medina in 622 CE.…”

“…In a relatively short time, he expelled or killed the Jews in Medina and established Islam as the only religion in the region." 40 Throughout his book, Kilpatrick argues that there is a dangerous historic link between migration and Islamic conquest. He claims that throughout the history of the Islam, hijra has always played a central role in the "islamization" of the host country or culture, especially when combined with non-assimilation and high birth rates for Muslims.…”
