Isolation and structural characterisation of a reactive chiral palladium(II) complex containing a ClO4 ligand

Asymmetric synthesis of a chiral hetero-bidentate As–P ligand containing both As and P-stereogenic centres

“…As observed in other analogous arsine complexes, the arsenic atom in DMPA is trans to the NMe 2 group by virtue of the hard soft donor preference exhibited by the chiral amine based auxiliary [4]. Treatment of the chloro complex (+)-2 with silver perchlorate yielded the intermediate cationic perchlorate species in essentially quantitative yield [9]. This highly reactive species was not isolated and was treated directly with a stoichiometric amount of phenyldivinylphosphine.…”

“…8(1) C(12)-As(1)-C (7) 77.4(2) C(14)-C(7)-As(1) 94.9(2) C(8)-C(7)- C(14) 111.9(3) C(8)-C(7)-As(1) 100. 9(3) C(10)-C(8)-C (7) 111.7(4) C(8)-C(10)-C (12) 112.0(4) C(13)-C (12) decomposed rapidly in solution. But interestingly, the retrodiene diiodo complex (+)-10 was subsequently obtained via an alternate pathway.…”

Asymmetric synthesis of a P-chiral heteroditopic ligand via chiral metal template promoted cycloaddition between 3,4-dimethyl-1-phenylphosphole and its sulfonated analog

“…It should be noted that the chloro ligand in (R c )-3 is stable and inert and therefore cannot be replaced by incoming organic substrates. Therefore treatment of this chloro species in dichloromethane with aqueous silver perchlorate provides access to the highly labile perchlorate analogue (R c )-4 in quantitative yield [31].…”

Design, Synthesis, and Stereochemical Evaluation of a Novel Chiral Amine–Palladacycle

“…The bond lengths and angles around Pd1 atom are all comparable to those of other dmpp complexes of α-arylalkylamine auxiliaries. [10] The complex has a distorted square-planar coordination geometry, with a tetrahedral distortion angle of 8.5°. Due to the fact that dmpp is smaller than PPh 3 , the angle C1-Pd1- .…”
