Neue optisch aktive Phosphoniumsalze als Phasentransferkatalysatoren sowie die Verwendung der korrespondierenden Phosphane in der asymmetrischen Katalyse
… The use of diphenylphosphino benzoic acid pentafluorophenol esters paved the way for the synthesis of a wide range of amides, which were obtained by conversion with diverse amines. It was found that sterically demanding substituents in alpha-position to the amide group led to the highest …

Molybdenum and tungsten alkylidene complexes for cis- and trans-selective ring-opening metathesis polymerization
… center. For the case of molybdenum, addition of pentafluorophenol to the diimido dialkyl precursor affords [chemical formula]. Dipyrrolide complexes for both Mo and W are synthesized and isolated as a 2,2'-bipyridine adduct. Addition of a sterically encumbered terphenol along with ZnCl₂(dioxane) …

CONSTRUCTING NANOSTRUCTURES WITH ATOMIC PRECISION: THE SYNTHESIS OF SPIROLIGOMER-BASED MACROCYCLES
… incorporated in bis-amino acids as well as a pentafluorophenol ester activation strategy that also has not been in the synthesis of spiroligomers. Finally, an extendable synthetic route to spiroligomer-based macrocycles has been developed and representative macrocycles have been synthesized. …

Electron Transfer and Other Reactions Using Atomic Metal Anions
The atomic metal anions Rb-, Cs-, Cu-, Ag- and Fe- have been generated in the gas phase and reacted with various neutral reactants in a triple quadrupole mass spectrometer. The metal anions were formed via electrospray ionization of the metal-oxalate solutions and form in gas phase between the …
