Present Communication

In an earlier paper* we have described the properties of all the members of the series of normal fatty acids which contain between 14 and 26 carbon atoms, and also of certain of their derivatives. The present communication deals with the redetermination on recently prepared specimens of the melting points and crystal spacings of some of these acids and, in continuation of the investigation, with the properties of all those of even carbon content containing between 28 and 38 carbon atoms, and the single acid with 46 carbon atoms. The properties of the corresponding ethyl esters, alcohols, iodides, and dicarboxylic acids obtained in the course of the syntheses of the fatty acids are also described.

Similar Series

SummaryThe series of normal saturated dicarboxylic acids, their diethyl esters and mono-ethyl esters have been investigated by means of X-rays, and from the measurement of the principal spacings a definite chain structure has been assigned to each series. Mathematical formulæ derived by Shearer for similar series of compounds have been applied to these structures, and the intensity distribution among the several orders of reflection from the principal planes calculated. These calculated results have been compared with those actually observed from the plates, and the agreement was found to be good in every case, thus confirming the chain structures assigned by the authors to the above series of compounds.

Dissipative (nonequilibrium) assembly powered by chemical fuels has great potential for the creation of new adaptive chemical systems. However, while molecular assembly at equilibrium is routinely used to prepare complex architectures from polyfunctional monomers, species formed out of equilibrium have, to this point, been structurally very simple. In most examples the fuel simply effects the formation of a single transient covalent bond. Here, we show that chemical fuels can assemble bifunctional components into macrocycles containing multiple transient bonds. Specifically, dicarboxylic acids give aqueous dianhydride macrocycles on treatment with a carbodiimide. The macrocycle is assembled efficiently as a consequence of both fuel-dependent and -independent mechanisms: it undergoes slower decomposition, building up as the fuel recycles the components, and is a favored product of the dynamic exchange of the anhydride bonds. These results create new possibilities for generating structurally sophisticated out-of-equilibrium species.
