We describe the synthesis of a series of interlocked structures from porphyrin-glycoluril cage compounds and bis(olefin)-terminated viologens by an olefin-metathesis protocol. The length of the chain connecting the olefin substituents with the violog

A ruthenium porphyrin functionalized with a cavity based on diphenylglycoluril is applied as a catalyst in carbenoid transfer reactions using α-diazoesters as substrates. The latter compounds contain a blocking group connected via an α,ω-dioxyalky

The cooperative binding effects of viologens and pyridines to a synthetic bivalent porphyrin receptor are used as a model system to study how the magnitudes of these effects relate to the experimentally obtained values. The full thermodynamic and kin

Bound to cooperate: Binding of dimethylviologen in the cavity of a Zn porphyrin host dramatically increases the affinity of the host for N-donating ligands and vice versa (see scheme). These positive heterotropic allosteric effects are exploited to d

The ethene complexes [MI(CH2CH2)]+ (M = Ir, Rh) can be oxygenated by molecular oxygen or air in the solid state, to form isolable unsubstituted 3-metalla-1,2-dioxolanes [MIII(CH2CH2OO-κ2C1,O2)]+. Such selectivity could not be achieved in solution. T

A ruthenium-carbene-stoppered [2]rotaxane acts an intermediate in the synthesis of porphyrin-containing [3]rotaxanes by an olefin-metathesis protocol. The thread of these [3]rotaxanes can be extended to a polybutadiene strand by using them as chain-t

Proposed as intermediates in the catalytic oxidation of olefins to ketones, 3-rhoda-1,2-dioxolanes (κ2 C1 ,O2 -2-peroxyethyl rhodium complexes) have now been prepared by oxygenation of solid [(N4 -ligand)RhI (ethene)]PF6 with air. This process leads
