Interplay of Olefin Metathesis and Multiple Hydrogen Bonding Interactions: Covalently Cross-linked Zippers
摘要:
Hydrogen-bonded zippers bearing terminal alkene groups were treated with Grubbs' catalyst, leading to covalently cross-linked zippers without violating H-bonding sequence specificity. The yield of a cross-linked zipper depended on the stability of its H-bonded precursor, with a weakly associating pair giving reasonable yields only at high concentrations while strongly associating pairs showed nearly quantitative yields. The Integration of thermodynamic (H-bonding) and kinetic (irreversible C=C bond formation) processes suggests the possibility of developing many different covalent association units for constructing molecular structures based on a self-assembling way.
