The substitution of primary or secondary alcohols with nucleophiles mediated by a redox
combination of a trialkylor triarylphosphine and a dialkyl azodicarboxylate is popularly …

Part of the renaissance in main group chemistry has been a result of the focus on reactivity.
This has led to the development of applications in stoichiometric reactivity and catalysis. In …

Prototypical Lewis acids, such as boranes, derive their reactivity from electronic
unsaturation. Here, we report the Lewis acidity and catalytic application of electronically …

The Mitsunobu reaction is a widely used and versatile method for the dehydrative oxidation–
reduction condensation of an acid/pronucleophile usually with a primary or secondary …

Phase transformations of metastable olivine might trigger deep-focus earthquakes (400 to
700 kilometers) in cold subducting lithosphere. To explore the feasibility of this mechanism …

The purpose of this critical review is to introduce the reader to an increasingly important
class of phenomena: enormous changes in rates of simple chemical reactions within …

Three-component coupling reactions between trialkylphosphines, methyl propiolates, and
aldehydes produced 1: 1: 1 dipolar adducts in moderate to excellent yields. The product …

Conspectus Historically, the chemistry of phosphate transfer a class of reactions
fundamental to the chemistry of Life has been discussed almost exclusively in terms of the …

We have quantum chemically studied the effect of various polar and apolar solvents on the
shape of the potential energy surface (PES) of a diverse collection of archetypal nucleophilic …

The use of trialkylphosphonium oxoborates (TOB) as catalysts is reported. The site-isolated
borate counter anion in a TOB catalyst increases the availability of C (sp3)–H to interact with …
