Structure and properties of arylnorbornyl palladacycles as stable models for catalytic intermediates

•Crystal structure of two arylnorbornyl palladacycles containing phen was reported.•The presence of an ortho methyl group does not influence the geometrical parameters.•Their geometry was compared with the geometry of analogous intermediates.

The solid state structure of two arylnorbornyl palladacycles containing phenanthroline as ancillary ligand was elucidated through X-ray diffraction analysis. Both compounds, the phenylnorbornyl palladacycle (1a) and the o-tolylnorbornyl palladacycle (1b), possess very similar geometrical parameters in spite of the presence of an ortho methyl group in 1b.

Graphical abstractThe solid state structure of two arylnorbornyl palladacycles containing phenanthroline as ancillary ligand was elucidated through X-ray diffraction analysis, to ascertain if their different behavior under catalytic conditions could be ascribed to differences in their structure.Figure optionsDownload full-size imageDownload as PowerPoint slide
