Abstract
A solvent-free multicomponent protocol for the rapid (<30 min) synthesis of pyridyl-functionalised [5]polynorbornane ligands is described in which both 1,3-dipolar cycloaddition and imide formation occur. The ligands produced by this approach have been incorporated into new Pd and Pt M1L2 chelate complexes as well as an M2L4 cage as elucidated from NMR spectroscopy, ESI-MS and computational data.
