Cis-trans isomerization and stability of substituted poly(phenylacetylene)s: effect of the ring substituent

The spontaneous cis to trans isomerization and autooxidation of the series of ring-substituted poly(phenylacetylene)s was studied. The influence of the character and the position of substituents on these processes ...

The cis/trans-isomerism on cobalt(III) complexes with 1,4,8,11-tetraazacyclotetradecane- 1,8-bis(methylphosphonic acid)

The X-ray structure determinations show that 1,4,8,11-tetraazacyclotetradecane-1,8-bis(methylphosphonic) acid H4L forms both cis- and trans-O,O isomeric complexes with Co(III). Orientation of the other donor atoms indicates...

Monitoring of peptide bond conformation in N-methylated peptides by RP-HPLC and NMR

Significant peak broadening was observed for some N-methylated peptides as a consequence of cis/trans isomerism of the peptide bond. Chromatographic behavior of the N-methylated peptides was compared with data obtained by N...
