Half-life times up to 4 days in DMSO at room temperature are observed for the decomposition of dimeric capsules of urea substituted calix[4]arenes held together by a combination of hydrogen bonds, mechanical entanglement and cation-π interactions.

It was established that the ease of noncatalytic addition of cyclic and acyclic partial phosphites to enamines is due to the H-donor capacity of the acids and to the degree of localization of the electron density at the C=C bond in the unsaturated partner.It was shown that cyclic phosphites add initially at the carbon-carbon multiple bond of the conjugated N-C=C-C=O system of enamino ketones with the final formation of bisphosphorylated derivatives.
