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

► Pd(II)-N-{2-(aryltelluro)ethyl}morpholine/piperidine complexes (1/2) synthesized. ► Their single crystal structures determined. ► PdTe NP's (~ 5 nm) formed in catalyzing C-N coupling with 1/2. ► Conversion was up to 93% in Heck coupling catalyzed with 0.005 mol% of 2.
