THE USE OF SO2Cl2 IN ORGANOMETALLIC CHEMISTRY. CONVENIENT HIGH YIELD SYNTHESES OF AND (M = Mn or Re)
Manning, A. R.,McNally, Gerald,Davis, Reg,Rowland, Christopher C.
, p. C15 - C16 (1983)
Depending on the substrate and the reaction conditions, SO2Cl2 is a useful reagent which brings about either chlorination or the formation of cationic species on reaction with transition metal carbonyl complexes.
Direct and high yield syntheses of Re2(CO)10 and Re(CO)5 Cl by sodium reduction of K2ReCl6 under CO

, p. 121 - 122 (1997)
A convenient procedure for the synthesis of the rhenium carbonyls Re2(CO)10 and Re(CO)5 Cl is reported. Sodium reduction of the easily available K2ReCl6, under CO presssure (2400 psi, 280°C (external temperature), THF as solvent) affords Re2(CO)10 and Re(CO)5Cl in 81% and 86% isolated yield, respectively. Depending on the hexachlororhenate:Na ratio, either carbonyl derivative can be obtained almost exclusively.
A Re(CO)5 fragment bonded to a polyhedral oligomeric hydroxysilsesquioxane as a model which gives further evidence to the existence of an unexpected Re(CO)5 surface species

Reaction of Re(CO)5O3SCF3 with (c-C6H11)7Si8O12O-Li+ at 273 K under a CO atmosphere affords the [Re(CO)5OR] (R = (c-C6H11)7Si8O12) derivative (1). 1 is the first example of a rhenium pentacarbonyl bearing an OR ligand (R = alkyl, aryl, or silyl) stable enough to be characterized, and it represents also the first molecular model of the surface [Re(CO)5OSi≡] species formed by reductive carbonylation of silica-supported [Re(CO)3OH]4. At room temperature, 1 loses one carbonyl ligand and dimerizes to afford {Re(CO)4[(μ-O)O12Si8(c-C6H11)7]}2 (2), which has been characterized by X-ray diffraction and is the first reported example of a rhenium tetracarbonyl μ-oxo-bridged dimer of the type [Re(CO)4(μ-OR)]2.

Multi-step and multi-component organometallic synthesis in one pot using orthogonal mechanochemical reactions
Hernandez, Jose G.,Butler, Ian S.,Friscic, Tomislav
, p. 3576 - 3582 (2014)
We demonstrate that the mechanochemical strategies for oxidative addition and ligand substitution on organometallic centers can be mutually orthogonal, permitting the rational design of multi-component mechanochemical reaction procedures for assembling complex or solution-sensitive organometallic species from three, four or even five components in one pot. The herein established synthetic procedures represent a new level of complexity in mechanochemical reactions by milling and are the first to combine redox and ligand substitution reactions into mechanochemical strategies for either one-pot sequential ( telescoping ) or one-pot multi-component syntheses. This ability to combine mechanochemical transformations has enabled the solvent-free, room-temperature syntheses of relatively complex organometallics directly for simple zerovalent metal carbonyls as the simplest precursors. In particular, we demonstrate the efficiency of mechanochemical oxidative addition by targeting selected pentacarbonyl halides (fluoride, chloride, bromide, iodide) of rhenium(i) and manganese(i), and illustrate the potential of multi-step organometallic mechanochemistry in the syntheses of selected fac-tricarbonyl complexes of these metals.

Paragraph 0066, (2018/04/11)
A composition comprising the following structure: (formula I) wherein Re represents a rhenium ion having a +1 charge; (formula II) represents an uncharged bidentate bicyclic ligand bonded to the rhenium (Re) by two ring nitrogen (N) atoms; and L is a neutral ligand independently selected from CO and neutral phosphine molecules, wherein at least one of the L groups is a CO molecule; and X- represents a non-coordinating monovalent anion; wherein (formula II) is unsubstituted or substituted on any of its two rings, and said neutral phosphine molecule may or may not contain a phosphorus atom as a ring phosphorus atom; provided that, if (formula II) is unsubstituted, then one or two of said L groups are selected from said neutral phosphine molecules, with the provision that at least one of the neutral phosphine molecules has a phosphorus atom as a ring phosphorus atom. Methods for treating cancer by administering the above complex are also disclosed.
