Microextraction and Analysis of PFC’s from Biota
Due to the environmental prevalence and potential harm of some perfluorocarbons (PFC’s), primarily perfluoro carboxylic acids and perfluoro sulfonic acids, the quantitation of these compounds in environmental and biological samples is an active area of research. A recent example of … Continue reading

Solvation-Mediated Biphasic Catalysis
Solvophobicity is a term that we’ve used often here on F-Blog to describe many of the behaviors of fluorous molecules in relation to partitioning. While terms such as “fluorous affinity” are also used, it’s not really technically correct. While dipole … Continue reading

Catalysis with Fluorous Bipyridine Ligands
A recent paper in Adv. Synthesis and Catalysis from two groups in Italy describe the use of fluorous substituted bipyridyls (bipy) as ligands of methyltrioxorhenium (MTO). The resulting fluorous catalysts were then used to catalyze the epoxidation of various olefins. … Continue reading

F-NH3
The formation and preparation of nitrogen containing molecules is one of obvious importance in organic chemistry and particularly in medicinal chemistry. There’s not many classes of drugs that don’t contain a nitrogen or two (steroids and prostaglandins come to mind) … Continue reading

FLLE for Analytical Sample Enrichment
Perfluorinated compounds (PFCs) such as perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) have been identified as bioaccumulative and environmentally persistent. The identification and detection of these compounds in environmental and other matrices is one of increasing importance. Detection of … Continue reading
