Use of Bromine and Bromo-Organic Compounds in Organic Synthesis
TL;DR: The use of bromine and different bromo-organic compounds in organic synthesis is outlined and the scope of these reagents for various organic transformations such as bromination, cohalogenation, oxidation, cyclization, ring-opening reactions, substitution, rearrangement, hydrolysis, catalysis, etc is described briefly.

TL;DR: The highly strained ingenane skeleton was constructed through an intramolecular cyclization reaction of an acetylene dicobalt complex followed by a rearrangement Reaction of an epoxy alcohol.

Complex of alpha-chymotrypsin and N-acetyl-L-leucyl-L-phenylalanyl trifluoromethyl ketone: structural studies with NMR spectroscopy.
TL;DR: Evidence is presented for the presence of an Asp-His H bond and protonation of the imidazole group of His-57 in the tetrahedral adduct, which indicates that the pKa of his-57 is elevated in a complex containing a tetrahed adduct.

Das Allopolarisierungs‐Prinzip. Substituenteneinflüsse auf Reaktionen ambifunktioneller Anionen
TL;DR: In this paper, the Anderung der Selektivitat is described as a Funktion der Aenerung der polaritat of ambifunktionelle Anionen, i.e., the relative Ladungsdichte P = lX/lY-X and Y are the potentiellen reaktiven Zentren.

The Concept of Allopolarization. Effects of Substituents on the Reactions of Ambifunctional Anions
TL;DR: The concept of allopolarization permits a description of substituent effects on kinetically controlled reactions: the change in selectivity is a function of change in polarity of the ambifunctional anions.
