The synthesis of sulfur ylide complexes of palladium, zinc and copper in water

Synthesis and reactions of some sulfur ylide complexes of palladium

“…The dihedral angle between the C(l)-PdC( 2 atom is 0.53 A above the C(l)-PdC(2) plane. This value is very close to the 0.55 A found in [Pd((CH,),(SO)(CH,))((CH,)(SO)(CH,),),II [4]. The two CH, groups are in the axial positions, such that the compound adopts the chair conformation.…”

“…In a previous report [2] we described the synthesis of sulfur ylide complexes by the phase transfer technique, a rarely used method [3]. Subsequently we found that some interesting metal complexes of sulfoxonium ylide could be prepared in aqueous solution [4]. Our continuing interest in metal ylide complexes, especially with the application of the phase transfer technique in their synthesis, has led us to study the reactions of these complexes, as made in our laboratory.…”

“…In this paper we also describe an X-ray diffraction study of [Pd((CH,),(SO)(CH3)), 1 which contains two bidentate sulfoxonium ylides. (3) were prepared by the methods developed in our laboratory [4]. [Pd((CH,),(SO)(CH,)),1 (4) was prepared according to our previous work [4] but was modified slightly so that a better yield was obtained.…”

“…(3) were prepared by the methods developed in our laboratory [4]. [Pd((CH,),(SO)(CH,)),1 (4) was prepared according to our previous work [4] but was modified slightly so that a better yield was obtained. Compound 1 (1.0 g, 1.5 mmol) and ((CH,),(SO))I (0.75 g, 3.4 mmol) were dissolved in 4 ml DMSO.…”

Ylide Ligands

“…The synthesis is carried out in aqueous media using phase transfer catalysis, starting from the sulfonium salt [Me 3 SO]X and the metal salt in presence of NaOH. This method tolerates the presence of a wide variety of functional groups and/or ancillary ligands L n [179][180][181][182][183]. It is very worthy of note that both the ylide ligands and the resulting complexes are water soluble.…”
