Macrocyclic Compounds for Corrosion-Wear

CORROSION 1990, 1990
Abstract The possible application of Schiff base compounds as corrosion- and wear-protective additives in lubricant formulations suitable for use at high temperatures (i.e., ≥200 °C) has been investigated. In addition to their planar structure and quadridentate metal-binding characteristics similar to those of the macrocyclic compounds ...

Diastereoisomeric Singly Bridged Cyclophosphazene-Macrocyclic Compounds

Inorganic Chemistry, 2002
31P NMR spectroscopy and added chiral shift reagent (CSR) or chiral solvating agent (CSA) have been used to show that unsymmetrically substituted singly bridged macrocyclic phosphazene compounds exist as 1:1 diastereoisomers of two racemic mixtures, in contrast to previous work (ref 2) on symmetrically substituted diastereoisomeric analogues, which ...

Distinguishing the topology of macrocyclic compounds and catenanes

International Journal of Mass Spectrometry, 2003
Abstract The paper explores different possibilities to distinguish macrocyclic oligolactam species with different molecular topologies by ESI mass spectrometry. Collision-induced fragmentation provides unambiguous fragmentation patterns: Monocyclic rings upon single and double protonation predominantly lose water molecules, while catenanes, i.e., two
