(+)-trans-Chlorido{2-[(R _p)-2-(methylsulfanyl)ferrocenyl]-2,5,6,7-tetrahydropyrrolo[1,2-c]imidazol-3-ylidene}bis(triphenylphosphane-κP)palladium(II) hexafluoridophosphate dichloroform disolvate

Abstract

A solvated palladium(II) complex bearing a planar chiral ferrocenyl pyrrolo­imidazolyl­idene (NHC) ligand, synthesized by oxidative addition of a chloro­imidazolium salt to Pd(PPh3)4, features a pendant thio­ether group that is not involved in coordination to Pd.

Constructing Organometallic Architectures from Aminoalkylidyne Diiron Complexes

“…On the other hand, amino‐ferrocenes 77 contain a pendant alkynyl chain and are obtained in moderate yields using two equivalents of propargyl alcohol (Scheme b) . Notably, this synthetic procedure allows the access to ferrocenes multi‐functionalized exclusively at the (C 1 –C 2 –C 3 )‐derived five‐membered ring, including N‐ and S‐substituted ferrocenes, which are quite rare . Furthermore, the vinyl‐alkylidene complex 32 (R = Me, R′ = Fc = ferrocenyl, R′′ = H) has been exploited as a starting material to prepare bis‐ferrocenes (upon reaction with a series of terminal alkynes) and a ter‐ferrocene by reaction with ethynylferrocene .…”
