The nonenzymatic replication of RNA oligonucleotides is thought to have played a key role in the origin of life prior to the evolution of ribozyme-catalyzed RNA replication. Although the copying of oligo-C templates by 2-methylimidazole-activated G monomers can be quite efficient, the copying of mixed sequence templates, especially those containing A and U, is particularly slow and error-prone....

Abstract The new Fe(II) complex [Fe(trident)(bmik)](ClO 4 ) 2 ( 1 (trident = bis(2-pyridylmethyl)benzylamine and bmik bis(1-methylimidazole)ketone) exhibits a change of magnetic moment in dichloromethane (DCM) solution upon addition pyridine which is attributed to the Coordination-Induced Spin State Switching effect (CISSS). By attaching photoisomerizable azopyridine sidegroup tridentate ligand...

A comparison between the reactivity behavior of two lutetium benzyl complexes supported by different ferrocene-diamide ligands towards aromatic N-heterocycles, such as 1-methylimidazole, isoquinoline, and pyridines, is presented. The two ferrocene-diamide ancillary ligands differ in their nitrogen-donor substituent: adamantyl for one and t-butyldimethylsilyl for the other. The synthesis and cha...

A recently described plant cell wall dissolution system has been modified to use perdeuterated solvents to allow direct in-NMR-tube dissolution and high-resolution solution-state NMR of the whole cell wall without derivatization. Finely ground cell wall material dissolves in a solvent system containing dimethylsulfoxide-d(6) and 1-methylimidazole-d(6) in a ratio of 4:1 (v/v), keeping wood compo...
