Palladiumd(II) complexes of N-{2-(aryltelluro)ethyl}morpholine/piperidine: Synthesis, structure, application in Heck coupling and unprecedented conversion into nano-sized PdTe

The complexes, [PdCl2(L)] (1-2) (L = N-{2-(aryltelluro)ethyl}morpholine/piperidine) have been synthesized and characterized by multi-nuclei NMR and single crystal X-ray crystallography. They on reaction with aryl chloride/bromide and morpholine/piperidine give similar to 5 nm size nano-particles of PdTe. The 0.005 mol% of 2 is suitable for Heck coupling (conversion up to 93%).
