Pd-II complexes of tridentate PCP N-heterocyclic carbene ligands: Structural aspects and application in asymmetric hydroamination of cyano olefins
The synthesis of the ligand precursor 1,3-bis{(R)-1-[(S)-2(diphenylphosphanyl)ferrocenyl]ethyl}imidazolium iodide ([PCPH]I,1) was extended to the electronically and sterically modified ligand precursors 1,3-bis{(R)-1-[(S)-2-{[3,5-bis(tri- fluoromethyl) phenyl] phosphanyl}ferrocenyl] ethyl}imidazolium iodide ([3,5-CF3-PCPH]I, 6), and 1,3-bis[(R)-1-{(S)-2[bis(3,5-dimethylphenyl)phosphanyl)ferrocenyl}ethyl]imidazolium iodide ([3,5-Me-PCPH]I, 7). Palladium complexes were prepared starting from [Pd(OAc)(2)](3) in THF to afford [PdI(PCP)]OAc (8), [Pd(OAc)(3,5-CF3-PCP)]I (9), and [PdI(3,5-Me-PCP)]OAc (10), in excellent yields. The crystal structures of the ligand precursor [3,5-CF3-PCPH]I (6), the complex [PdI(3,5-CF3-PCP)]PF6 (14), as well as the dicationic complex [Pd(NCCH3)(PCP)](PF6)(2) (11), were determined by X-ray diffraction. Complex 11 and its derivative [Pd(NCCH3)(3,5-Me-PCP)](PF6)(2) (13) have been tested as catalysts in the asymmetric addition of, for example, thiomorpholine to methacrylonitrile giving selectivities up to 63 and 75 % ee, respectively, at -80 degrees C.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 119-47-1. Formula: C23H32O2.
