Synthesis and characterization of scandium complexes with reduced ligands: Crystal structures of Cp∗ScI2, [Cp∗ScI(bpy)]2, and [Cp∗ScCl(bpy)]2
TL;DR: In this paper, the synthesis and characterization of complexes containing a Cp∗Sc(R2bpy) motif are described, and the bipyridine ligands in 5 and 7 are arranged co-facially and are in close proximity, suggesting the presence of a π−π interaction.

β-Hydrogen Abstraction of an Ethyl Group Provides Entry to Titanium and Zirconium Ethylene Complexes
TL;DR: In this article, it was shown that α-abstraction is not a pathway to ethylene formation in trichloride complexes and showed that β-hydrogen abstraction is not necessary.

Electronic spectra of alternant hydrocarbon mononegative ions
TL;DR: In this article, the electronic spectra of the mononegative ions of naphthalene, anthracene, tetracene and phenanthrene, pyrene, perylene, biphenyl, terphenyl and quater-phenyl have been qualitatively interpreted with the aid of L.C.O. calculations including configuration interaction.
