Chloromethyl and methoxymethyl transition metal complexes : an investigation into their synthesis and reactivity
… and the new methoxymethyl The existence of rotational isomerism in the complexes [Ru(Cp)(CO)₂CH₂ocH₃] and the previously reported [Fe(Cp)(CO)₂CH₂OCH₃],⁴⁸ is proposed on the basis of infrared data. Mass spectra of several methoxymethyl and chloromethyl transition metal complexes have been …

Studies of the oxidation of zinc dialkyldithiophosphates and related compounds
… dithiophosphoric arids (RO)2P(:S)SH exhibit rotational isomerism about P-S and P-0 bonds. Temperature-dependence studies of 1 r (SH) and -(P-S) band intensities indicate LH for the equilibria to be 2.5 kJ mol-1,R= iso-propyl ; 3 kJmol-1 nice, R=n-butyl; 4.5 kJ mol-1, R= n-octyl. Thin film …

Synthesis of Insecticidal Mono- and Diacylhydrazines for Disruption of K+ Voltage-Gated Channels, and Elucidation of Regiochemistry and Conformational Isomerism by NMR Spectroscopy and Computation
… against An. gambiae, NMR spectroscopy revealed rotational isomerisms of two types: chiral helicity (M)/(P) and acyl (E)/(Z)-isomerism due to hindered rotation. Variable temperature NMR allowed the measurement of N-N bond rotational barriers, as well as estimate the barrier of (E)/(Z) …
