Carboxylic Acid Groups

A comparative study of bismuth complexation by various porphyrins which differ according to the structural scaffold – either picket(s) or strap(s) – that deliver the carboxylic acid groups close to the metal, has been performed. Unlike strapped porphyrins, and although more flexible, the picket ligands do not lead to more stable bismuth complexes.

The One

A comparative study of the gaseous oxidation of N - methyl diethylamine and N -ethyl dimethylamine shows that the former compound closely resembles triethylamine in its general behaviour, while the latter compound exhibits a striking similarity to trimethylamine. With both the mixed tertiary amines a reaction occurs which leads to the formation of secondary amine, but which rapidly becomes self-inhibited as oxidation proceeds. Only with N -methyl dimethylamine, however, are substantial amounts of primary amine formed among the products of slow combustion. A possible explanation of this last difference is that only peroxy-radicals derived from tertiary amines containing at least two ethyl groups can, on steric grounds, readily undergo intramolecular attack to yield monoalkylamines. The apparent ease of such a reaction during the oxidation of N -methyl diethylamine and triethylamine may thus account for the marked contrast between the behaviour of these two compounds on the one hand and that of N -ethyl dimethylamine and trimethylamine on the other.
