Abstract: A study was conducted to demonstrate the coordination chemistry remote and abnormal dicarbenes and their use as a new class of organometallic spacers for the formation of di- and tetranuclear PdII complexes. The suitable ligand precursors with bridges of different lengths were obtained through alkylation of 4,4'-di-iododipyrazoles with Me3OBF4 as white solids in moderate to high yields of 86%, 93% and 62%. The topology of ligand precursors ensured the formation of di- or polynuclear complexes and prevented chelation of the resulting dicarbenes. Dipyrazolium salt was reacted with a pre-mixed solution of [Pd2(dba)3]/PPh3 to synthesize a dinuclear PdII -dicarbene complex. It was also demonstrated that novel dipyrazolin-4-ylidenes were versatile building-blocks for di- or tetranuclear architectures.
