Catalytic Silylation of Alkynyl C(sp)–H bonds with tert‐Butyl‐Substituted Silyldiazenes
ChemCatChem, Accepted Article.The deprotonative silylation of terminal alkynes constitutes one of the most privileged strategies to prepare alkynylsilanes owing to the relatively high acidity of C(sp)–H bonds. While the key deprotonation step is usually mediated by stoichiometric amounts of strong Brønsted bases (e.g.

Ferrocene derivatives with planar chirality and their enantioseparation by liquid‐phase techniques
ELECTROPHORESIS, Volume 44, Issue 1-2, Page 158-189, January 2023., 2023 Abstract In the last decade, planar chiral ferrocenes have attracted a growing interest in several fields, particularly in asymmetric catalysis, medicinal chemistry, chiroptical spectroscopy and electrochemistry. In this frame, the access to pure or enriched enantiomers of planar chiral ferrocenes has become essential, relying on the availability of ...

Dual Nickel/Titanium Catalyzed Cross‐Electrophile Coupling of Thioesters with Benzylic Alcohols
ChemCatChem, Accepted Article.This work focuses on the development of a new method for ketone synthesis via cross electrophile coupling (XEC) starting from widely available and low‐cost reagents. We demonstrate the XEC of benzylic alcohols and thioesters under reductive conditions and in the presence of trimethylsilyl chloride (TMSCl) using a dual catalytic system consisting of an ...

Gas-liquid chromatography-mass spectrometry of synthetic ceramides
Journal of Lipid Research, 1969 Two series of ceramides with either sphingosine (sphing-4-enine) or sphinganine as base and with one of the saturated fatty acids C16, C18, C20, C22, C24, C26, or oleic acid were analyzed as the 1,3-di-O-trimethylsilyl ether derivatives by gas ...

Palladium‐Catalyzed Allylation of (Hetero)Aryl Fluorosulfates
ChemCatChem, Accepted Article.Reported herein is the palladium‐catalyzed allylation of (hetero)aryl fluorosulfates. When employing a [Pd(cinnamyl)Cl]2/XantPhos catalyst system and using either allyl pinacolboronate or potassium allyltrifluoroborate, allyl (hetero)arene products were successfully prepared and isolated in synthetically useful yields, including examples featuring ...
