Phosphonium Salt Organocatalysis
Advanced Synthesis & Catalysis, 2009AbstractThe field of organocatalysis is growing rapidly and attracts an increasing number of research groups. Most organocatalysts can be classified as Lewis bases, Lewis acids, Brønsted acids and Brønsted bases. However, examples of Lewis acid organocatalysis under homogeneous conditions are comparatively rare.

Phosphonium salt intercalated montmorillonites
Applied Clay Science, 2009Abstract Tri-phenyl vinylbenzyl phosphonium chloride and tetraoctyl phosphonium bromide salts have been used as intercalant agents for Na-montmorillonite. Fourier Transform Infrared spectroscopy (FTIR) and Thermogravimetric Analysis coupled with Mass-spectrometry (TG/DTG-MS) were used to characterize the modified montmorillonites and the thermal ...
