An XPS study of the thermal degradation of polystyrene-clay nanocomposites [PDF]

, 2002
X-ray photoelectron spectroscopy, XPS, has been used to examine several polystyrene-clay nanocomposites. The accumulation of oxygen, from the almuniosilicate, on the surface of the polymer was observed, along with the loss of carbon.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

Chemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...

Rigid Ligand Environments at Beryllium, From Spectroscopic Probes to Small Molecule Activation

European Journal of Inorganic Chemistry, EarlyView.
Due to the high rigidity and definition of beryllium scorpionate complexes, they can be used to study metal‐pseudohalide and ‐carbon bonds in detail. Furthermore, these compounds can be used to activate small molecules and exhibit unprecedented transmetalation reactions. In beryllium scorpionate complexes, three of the four available coordination sites
