Synthesis and structure of mono- and di-nuclear complexes of ortho-palladated derived from phosphorus ylides

New Pd‐phosphorus ylide complexes based on FC60 as heterogeneous nano‐catalyst for H/D exchange reaction

“…Coordination of ylide through the methinic carbon atom to Pd center leads to conversion of P=C double bond to P-C single bond, which causes a large downfield shift for the phosphorus atom of PCH group. [20] Hence, the 31 P NMR spectra represent a singlet peak around 24 ppm for all complexes, which shifted to downfield in comparison with parent ylides (12-14 ppm) ( Figure 2).…”

31P NMR study of the stoichiometry and stability of several mercury(II) halides with a phosphorus ylide in different solvents

“…Ligand (L) was prepared as previously described [21]. AN, DMSO, DMF and THF were commercially available from the Aldrich and used as received.…”

Synthesis, spectral characterization, and X-ray crystal structure of Pd(II) complexes containing the orthometallated C,C-chelating ligand C6H4-PPh2C(H)C(O)CH2Cl

“…13 C { 1 H} NMR spectra of 4-6 show signals due to the ylidic carbon at 37.1 ( 1 J pc = 56 Hz), 36.5 ( 1 J pc = 57 Hz), and 37.5 ppm ( 1 J pc = 57 Hz), respectively, with characteristic coupling constants for a C-bonded ylide [32,35,41].…”
