ortho-Substituted 1,8-Diarylnaphthalenes: Conformational Thermodynamics and Kinetics
摘要:
1,8-Diarylnaphthalenes show interesting potential as chiral sensors, environment sensors and stereodynamic switches. The kinetics and thermodynamics of the conformational equilibria of two such compounds are described. These compounds, along with others reported previously, show that several features can be used to tune the conformational behaviour of these compounds, giving the possibility to design molecules for specific applications in the future.

The synthesis of substituted 1,8-diarylnaphthalenes is reported. A bis-Suzuki coupling strategy starting from 1,8-di-bromonaphthalene provides a useful and general route to the 1,8-diarylnaphthalene scaffold. In this context, N-heterocyclic benzhydrylamine ligands, in combination with PdCl 2 , were found to form especially efficient catalytic systems. The syn/anti ratios were determined in solution
