Abstract
Binary sulfur fluorides exhibit an interesting reactivity towards transition metal complexes. They open up routes for the generation of sulfur‐containing building blocks. Often ligands with particular properties can be constructed. This includes their ability to transfer sulfur atoms or polysulfide units as well as fluorination reactions. This Minireview provides an insight into the reactivity of the binary and ternary sulfur halides S2Cl2, SCl2, SF4, SF6 and SF5Cl towards transition‐metal compounds.

Abstract
New unsymmetrical hydroxyferrocenes were synthesised from dibromoferrocene. The oxygen heteroatom was introduced via lithiation and quenching with bis-trimethylsilylperoxide followed by hydrolysis to unmask the hydroxyl functionality. The coordination chemistry of 1'-(diphenylphosphino)-1-hydroxyferrocene 2 was explored with palladium and rhodium precursors. A dinuclear palladium methyl complex with bridging ferrocenyloxo groups was obtained from the reaction between 2 and (cyclooctadiene)methylchloropalladium(II). With tetracarbonyldichlorodirhodium(I), two complexes were isolated. The major product was a bis ligand cis phosphine ligated complex with one ligand bound in a chelating mode and one with a pendant hydroxyl group. A minor product was crystallographically characterised as a dinuclear ferrocenyloxo-bridged rhodium carbonyl complex. The coordination chemistry of 2 and the corresponding phosphine oxide 3 was examined with group 4 metals and the resulting complexes examined as ethylene polymerisation catalysts. The ligands were found to bind in either a chelating fashion or with pendant phosphine donors. In all cases, low to moderately active ethylene polymerisation catalysts were found. The catalysts were very unstable and catalyst residues were observed in the isolated polymer indicating a short catalyst lifetime.

Abstract
The synthesis of the benzyl phosphinothioether derivatives Ph(2)PCH(2)CH(Et)SR and their corresponding palladium complexes are reported, where R = CH(2)Ph, R = CH(2)-3,5-Me-C(6)H(3) and R = 1-CH(2)C(10)H(7)(5). Crystallographic data obtained for the complexes Pd(3)Cl(2) and Pd(4)Cl(2) show intra- and inter-molecular pi-pi interactions between the aromatic rings on the P and S substituents, and NOE experiments for Pd(4)Cl(2) show that these interactions persist in solution. The performance of the phosphinothioether palladium complexes in aryl-aryl cross-coupling reactions is compared with that of the corresponding complex of the parent phosphinothiolato ligand Ph(2)PCH(2)CH(Et)S(-)(1). High turnover numbers up to 2000000 are reported for the coupling of bromobenzene, using the palladium dimer [Pd(1)I](2) as the catalyst precursor. Kinetic studies show a linear dependence of the reaction on catalyst loading. The effect of other variables on the cross-coupling reaction, such as temperature, solvent and base, is also reported.

Abstract
Donor properties of 1-(diphenylphosphanyl)-1'-vinylferrocene (1) were investigated in a series of reactions with palladium(II), rhodium(I), and copper(I) compounds. In all complexes obtained, compound 1 coordinates exclusively as a monodentate phosphorus donor, giving trans-[PdCl2(1-κP)2] (3) with [PdCl2(cod)], [PdCl(LNC)(1-κP)] (4) with [{Pd(LNC)}2(μ-Cl)2], and trans-[RhCl(CO)(1-κP)2] (5) with [{Rh(CO)2}2(μ-Cl)2] (cod = cycloocta-1,5-diene, LNC = 2-[(dimethylamino)methyl-κN]phenyl-κC1). Copper(I) precursors CuI and [Cu(MeCN)4]PF6 reacted with 1 in a similar manner, yielding at appropriate molar ratios heterocubane [(μ3-I)4{Cu(1-κP)}4] (6) and the bis(phosphane) complex [Cu(MeCN)(1-κP)2]PF6 (7), respectively. The structures of 1-(diphenylthiophosphoryl)-1'-vinylferrocene (2), 3, 4·CHCl3, 6·C6H6, and 7 have been determined by single-crystal X-ray diffraction.

Abstract
New unsymmetrical S/O 1,1'-disubstituted ferrocenediyl ethers and hydroxides have been synthesised. The coordination chemistry of 1-(methylsulfanyl)-1'-(methoxy)ferrocene has been investigated with palladium(II) and platinum(II) precursors. With palladium(II), a bis-mu-chloro-bridged dimeric complex was obtained with the ligand bound solely through the thioether donor group. With platinum(II), a bis-ligand trans-sulfur ligated complex was obtained and structurally characterised.

Abstract
The reaction of the unsymmetrical ligands 1-diphenylphosphino-1'-(phenylsulfanyl)ferrocene and 1-diphenylphosphino-1'-(phenylselenyl)ferrocene, Fc(EPh)PPh2(E = S, Se), with several group 11 metal derivatives leads to the synthesis of complexes of the type [MX{Fc(EPh)PPh2}](M = Au, X = Cl, C6F5; M = Ag, X = OTf), (OTf = trifluoromethanesulfonate), [M{Fc(EPh)PPh2}2]X (M = Au, X = ClO4; M = Ag, X = OTf), [M(PPh3){Fc(EPh)PPh2}]OTf (M = Au, Ag), [Au2{Fc(SPh)PPh2}2](ClO4)2, [Au(C6F5)2{Fc(SePh)PPh2}]ClO4, [Au(C6F5)3{Fc(EPh)PPh2}], [Au2(C6F5)6{Fc(SePh)PPh2}] or [Cu{Fc(EPh)PPh2}2]PF6(E = S, Se). In these complexes coordination depends upon the metal centre; with gold it takes place predominantly to the phosphorus atom and with silver and copper to both phosphorus and chalcogen atoms. The treatment of some of the gold complexes with other metal centres affords heterometallic derivatives that in some cases are in equilibrium with the homometallic derivatives. Several compounds have been characterized by X-ray diffraction, four pairs of homologous compounds, yet not a single pair is isotypic. In many of them a three dimensional network is formed through secondary bonds such as hydrogen bonds, Au...Cl or Au...Se interactions. The complex [Ag(OTf){Fc(SePh)PPh2}] forms one-dimensional chains through trifluoromethanesulfonate bridging ligands.

Abstract
A series of metal-centered ferrocene compounds has been designed by using 5-ferrocenylpyrimidine (L1) and ferrocenylpyrazine (L2). These ligands, when combined with transition metal salts, produce mixed-metal polynuclear complexes with structural diversity. Reaction of L1 with M(SCN)(2) (M = Ni, Co) produces the pinwheel-like 4:1 complexes (L1)(4).M(SCN)(2), while reactions of L1 and L2 with Cu(NO(3))(2) give the 3:1 complex (L1)(3).Cu(NO(3))(2) and the 2:1 complex (L2)(2).Cu(NO(3))(2), respectively. Reactions of L1 and L2 with M(hfac)(2) (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonate, M = Mn, Ni, Cu, Zn) produce 2:1 complexes (L)(2).M(hfac)(2) with cis and trans configurations, respectively. Crystal structures as well as solid-state electrochemical properties of these redox active complexes were investigated.
