Guanidinium Promoted Cleavage of Phosphoric Diesters: Kinetic Investigations and Calculations Provide Indications on the Operating Mechanism.

Journal of Organic Chemistry, 2017
The catalytic activity of the guanidinium units toward the cleavage of phosphoric diesters is deeply investigated both with kinetic experiments and DFT calculations. The first part of the investigation aims to determine how the structure of the substrate

Phosphoric Acid Based Heterodimers in Asymmetric Catalysis

Synlett : Accounts and Rapid Communications in Synthetic Organic Chemistry, 2016
Chiral phosphoric acid diesters arguably constitute the most exploited class of catalysts in asymmetric Brønsted acid catalysis. Despite being highly investigated for their acidic properties, these compounds display an amphoteric nature, which has ...

In the Bottlebrush Garden: The Structural Aspects of Coordination Polymer Phases formed in Lanthanide Extraction with Alkyl Phosphoric Acids.

Journal of Physical Chemistry B, 2015
Coordination polymers (CPs) of metal ions are central to a large variety of applications, such as catalysis and separations. These polymers frequently occur as amorphous solids that segregate from solution.
