Investigation of the structure and magnetism in lanthanide β-triketonate tetranuclear assemblies
Reid, Brodie L.,Woodward, Robert C.,Fuller, Rebecca O.,Sobolev, Alexandre N.,Skelton, Brian W.,Ogden, Mark I.,Massi, Massimiliano
, p. 1852 - 1863 (2016)
The preparation of discrete tetranuclear lanthanide/alkali metal (Ae) assemblies bearing a tribenzoylmethane ligand (LH) is discussed. These assemblies have the general formula [Ln(Ae·HOEt)(L)4]2, where Ln3+ = Gd3+/s
Lanthanoid β-triketonates: A new class of highly efficient NIR emitters for bright NIR-OLEDs
Reid, Brodie L.,Stagni, Stefano,Malicka, Joanna M.,Cocchi, Massimo,Hanan, Garry S.,Ogden, Mark I.,Massi, Massimiliano
, p. 11580 - 11582 (2014)
The reaction of hydrated YbCl3 with potassium tribenzoylmethanide yields a new bimetallic tetranuclear Yb3+/K+ assembly. This species not only possesses the longest excited state lifetime and quantum yield reported for the Yb3+
An old story in new light: X-ray powder diffraction provides novel insights into a long-known organic solid-state rearrangement reaction
Halasz, Ivan,Cindro, Nikola,Dinnebier, Robert E.,Vancik, Hrvoj
, p. 187 - 192 (2013/11/06)
The first in situ diffraction study of the long-known solid-state rearrangement of p-bromobenzeneazotribenzoylmethane is reported. This proof-of-principle study demonstrates how modern laboratory X-ray powder diffraction, accompanied by up-to-date processing tools, can be used to monitor and describe mechanisms of organic solid-state reactions while it also underpins its necessity for structural characterisation of in situ formed crystalline phases.
FLUORIDE ION INDUCED REACTIONS OF ORGANOSILANES: THE PREPARATION OF MONO AND DICARBONYL COMPOUNDS FROM β-KETOSILANES.
Fiorenza, Mariella,Mordini, Alessandro,Papaleo, Sandro,Pastorelli, Stefania,Ricci, Alfredo
, p. 787 - 788 (2007/10/02)
β-ketosilanes react with a variety of carbon electrophiles in the presence of CsF to give mono- and dicarbonyl derivatives in reasonably good yields.
O-Acylation using organothallium compounds
-
, (2008/06/13)
Thallous salts of β-dicarbonyl compounds, prepared by reaction of the β-dicarbonyl compounds with a thallous alkoxide, are treated with alkyl halides to give C-alkyl products in high yield, with acyl halides at room temperature to give C-acyl products, and with acyl halides at low temperatures to give O-acyl products. Thallous phenolates are esterified with acyl or aroyl halides. Anhydrides are also prepared, as are biaryls and bi-sec-alkyls. N-Heterocyclics, including purines and pyrimidines, are N-alkylated. Lactams are O-acylated or N-alkylated.
