An electron rich porous metal-organic framework (MOF) has been synthesized, which acts as an effective heterogeneous catalyst for Diels-Alder reactions through encapsulation of the reactants in confined nano-channels of the framework.

1,2-Dibenzoyl-1-tert-butylhydrazine (RH-5849) and related\ N-alkyl-N,N'-diacylhydrazines are environmentally benign insect growth regulators. Herein, we show that an unusual nN(amide) {\textrightarrow} π*Ar\ interaction mediated by a hydrazide amide nitrogen atom plays a crucial role in stabilizing their biologically active trans{\textendash}cis (t{\textendash}c) rotameric conformations. We provide NMR and IR spectroscopic evidence for the presence of these interactions, which is also supported by X-ray crystallographic and computational studies.
