Abstract
The construction of biomolecular, supramolecular, nano-molecular structures and host-guest interaction occurs by composite of many interactions, i.e., electrostatic, cation-dipole, hydrogen bond, van der Waals, π-_π , cation-π, XH-π, etc. Some of these can be seen in host-guest chemistry, sometimes in almost pure form: the convergence of binding sites and rigid geometry, and isolated environments make it possible. In this review, the author shows several interactions observed in host-guest complexes. The macropolycyclic compounds, composed of aromatic rings and hetero atoms, formed various kinds of inclusion complexes and these contain several interaction, i.e., cation-dipole (-O×××M+, -N×××M+, CF ×××M+), hydrogen bond (-N×××HX, C-F×××HX), Ag-Ag metal bond, cation-π, and coordination bond.
Keywords: cation-dipole interaction, nitrogen, diethyleneoxa, azacyclophane, deprotonation, complexation, macrocyclic compounds, coulombic interaction, nmr, hydrocarbon

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
