Abstract

The fluorosulfur containing pincer ligands 1,3-(CH 2 SR f ) 2 C 6 H 4 [R f = C 6 F 5 (1) and 4-HC 6 F 4 (2)] and 1,2,4,5-(CH 2 SR f ) 4 C 6 H 2 [R f = C 6 F 5 (3) and 4-HC 6 F 4 (4)] have been prepared by treatment of 1,3-(CH 2 Br) 2 C 6 H 4 or 1,2,4,5-(CH 2 Br) 4 C 6 H 2 with the corresponding lead thiolate Pb(SR f ) 2 .

Recent Advances in Catalysis with Transition‐Metal Pincer Compounds

“…The number of contributions from different research groups around the world has enabled the preparation of pincer catalysts with several topologies . Thus, Figure shows some representative examples of a wide variety of pincer complexes employed in Mizoroki–Heck couplings, including SCS, (NHC)C(NHC), (NHC)N(NHC), as well as some hemilabile unsymmetrical models of pincer ligands…”

1,3-Bis[(naphthalen-2-ylsulfanyl)methyl]benzene

“…For information on pincer compounds, see: Albrecht & Morales-Morales (2009); Arroyo et al (2003); Morales-Morales (2004, 2009; Morales-Morales & Jensen (2007).…”

“…Among these species, those including sulfur as donor atom have been scarcely studied (Arroyo et al, 2003), mostly due to the well known tendency of sulfur to kill the activity of homogeneous catalysts. Thus, following our continuous interest in the synthesis of pincer type ligands we report the crystal structure of the potentially pincer sulfur based ligand 1,3-bis((naphthalen-2-ylthio)methyl)benzene.…”

Synthesis of fluorinated trithioether compounds

“…In addition, following our interest in transition metal complexes with fluorinated ligands [27], and the synthesis of fluorinated sulfides [28] to complex transition metal ions, here we report the synthesis, and structure of tripodal fluorinated trithioether compounds based on a benzene core. Some reports show coordination of analogous tripodal non-fluorinated trithioether molecules to transition metal ions [29][30][31], and a recent study [32] exploring the reactivity of related monothioether ligands bearing perfluorinated aryl substituents towards Pd(II) and Pt(II) has demonstrated their ability to coordinate transition metals, which increases our interest in the study of potential fluorinated trithioether ligands.…”
