Activation and Derivatization of Perfluoro(methyl Vinyl Ether) by a Rh(I) Germyl Complex

European Journal of Inorganic Chemistry, EarlyView.
Treatment of the rhodium (I) germyl complex [Rh(GePh3)(PEt3)3] with perfluoro(methyl vinyl ether) [PMVE] resulted in CO and CF bond cleavage and decarbonylation reactions, to yield trans‐[Rh(CFCF2)(CO)(PEt3)2] and germylated species including fluorogermane FGePh3, and fluoroalkene CF(GePh3)CF2.

Cholesteryl Fatty Acid Esters and Free Cholesterol in Food of Animal Origin

European Journal of Lipid Science and Technology, EarlyView.
Cholesterol occurs in free (bioavailable) and esterified (transport/storage) forms. Here, we present a method that allows both forms to be determined independently. Finally, the quantities of free and esterified cholesterol were determined in several meat, animal fat, and cheese samples.

Intra‐ and Intermolecular Glycosylation of d‐Idopyranosyl and 6‐Deoxy‐d‐ido‐heptopyranosyl Donors: Toward the Repeating Unit of Campylobacter jejuni HS:4c Capsular Polysaccharide

European Journal of Organic Chemistry, EarlyView.
A comprehensive glycosylation study of diversely protected and activated d‐idopyranosyl and 6‐deoxy‐d‐ido‐heptopyranosyl donors using intra‐ and intermolecular coupling strategies is reported. Intramolecular aglycon delivery afforded 1,2‐cis‐β‐idopyranosides, while intermolecular glycosylation yielded chromatographically separable α‐ and β‐linked ...
