Synthesis and single crystal X-ray structures of N,N′-bis(diphenylphosphinothioyl)piperzine and bis(diphenylphosphinoselenoyl)piperzine
摘要:
The reaction of N, N'-bis(diphenylphosphino) piperzine with elemental sulfur or selenium in toluene under refluxing conditions afforded Ph2P(S)N(C4H8)NP(S)Ph-2 or Ph2P(Se) N(C4H8)NP(Se)Ph-2 in a quantitative yield. The molecular structures were determined by X-ray studies.

Reaction of piperazine or homopiperazine with R2PCl [R2=Ph2, OC2H4O, OC6H4O] gives six new bidentate phosphines. Simple bis-chelate and bridging complexes with demonstrative Mo(0), Pd(II), Pt(II) and Ru(II) centres are reported. The crystal structures of Ph2P(O)N(C2H4)2P(O)Ph2, cis-[PdCl2Ph2PN(C2H4)2NPPh2}] (7) and cis-[PtCl2Ph2PN(C5H10)NPPh2}][PtcodCl2]2 (15) are reported. In Ph2P(O)N(C2H4)2P(O)Ph2

Luminescent copper(I) complexes presenting thermally activated delayed fluorescence (TADF) have drawn attention as emitters for organic light emitting diodes (OLEDs). While the majority of ligands used have nitrogen as donoratoms, in this work, we report the synthesis and characterization of three copper(I) complexes with the diimine ligand 1,10-phenanthroline and aminophosphine-derived ligands containing

The present invention relates to the use of aromatic P-piperazine-compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo-and copolymers, polycondensates, such as polyamines or polyesters and duroplastic polymers, such as polyepoxides.
