“…There are only a few examples of structurally characterized oxidorhenium(V) complexes with isocyanides. Most of them possess {ReO 2 } + or {Re 2 O 3 } 4+ cores, [23][24][25][26] which is a common structural feature of such complexes with neutral ligands and is also frequently found with related amines, imines or chelating phosphines. [27] To the best of our knowledge, there are only two reports about monooxidorhenium(V) complexes with isocyanide ligands: [26,28] Herein, we report an initial survey of reactions between m-terphenyl isocyanides and oxorhenium(V) complexes.…”

Reactions of the sterically encumbered m‐terphenyl isocyanides CNArDipp2 (Dipp = 2,6‐diisopropylphenyl) and CNArMes2 (Mes = 2,4,6‐trimethylphenyl) with (NBu4)[ReOCl4] in CH2Cl2 form stable complexes of the composition (NBu4)[ReOCl3(CNArR)] or [ReOCl3(CNArR)2] depending on the amount of isocyanide added. In the [ReOCl3(CNArR)2] complexes, cis coordination of the two isocyanides is observed for CNArMes2, while the sterically more demanding CNArDIPP2 ligands are found in trans positions. The rhenium(III) species [ReCl3(PPh3)(CNArMes2)2] was obtained from the reaction of [ReOCl3(PPh3)2] and CNArMes2. The ν(CN) IR frequencies measured for the ReV complexes appear at higher wavenumbers than for the uncoordinated isocyanides, which suggests a low degree of backdonation into anti‐bonding orbitals of these ligands.
