Big and little Meccano
TL;DR: The emergence of the mechanical bond during the past 25 years is giving chemistry a fillip in more ways than one as discussed by the authors, and it is providing a new lease of life to chemical synthesis where mechanical bond formation occurs as a consequence of the all-important templation orchestrated by molecular recognition and self-assembly.

TL;DR: A linear Hammett relationship (rho = 0.59) between log K(a) and sigma(p)(+) values of substituents indicates that the diaryl-lambda(3)-iodanes with electropositive iodine(III) interact more efficiently with 18C6.

Intermolecular hypervalent I(III)⋯O interactions: A new driving force for complexation of crown ethers
TL;DR: In this paper, the authors show that intermolecular hypervalent I(III)⋯O interactions play an essential role in the complexation of organo-λ3-iodanes with crown ethers.
