“…[17] Interestingly, SO can be stabilized as a ligand in the coordination sphere of metal complexes. [16,[18][19] In general, the μ 2 bridging mode [20] is much more often observed than SO as a terminal [21] or μ 3 bridging ligand. [22] Recently, adduct formation of SO with carbenes has been reported.…”

During our studies towards the preparation of the pentagonal‐pyramidal hexamethylbenzene dication C6(CH3)62+, we isolated the unprecedented dicationic species C6(CH3)6SO2+ (AsF6−)2 from the reaction of hexamethylbenzene with a mixture of anhydrous HF, AsF5, and liquid SO2. This compound can be understood as a complex of unknown SO2+ with hexamethylbenzene. Herein, we report on its synthesis, molecular structure, and spectroscopic characterization.

“…[2] The SO ligand was often generated from thionyl chloride by reduction in the coordination sphere of the metal atom. Complexes with terminal S-bound sulfur monoxide are known [3] as well as with a bridging ligand between two metal atoms (e.g. [Cp(CO) 2 Mn] 2 SO [4] ).…”

An Adduct of Sulfur Monoxide to a Frustrated Sn/P Lewis Pair

et al. 2020

The geminal frustrated Lewis pair (F5C2)3SnCH2P(tBu)2 (1) reacted with N‐sulfinylaniline PhNSO to afford the first sulfur monoxide adduct of a main group metal, (F5C2)3SnCH2P(tBu)2⋅SO (2), which contains a SnCPSO ring. The second product is a phenylnitrene adduct of 1. The surprising stability of 2 was compared with the stabilities of the so far inaccessible O2 and S2 adducts of 1. Attempts to prepare these from 1 and the elemental chalcogens (O2, S8, Se∞, Te∞) led to four‐membered SnCPE ring systems. Quantum‐chemical investigations of 2 demonstrate the bond polarity of the SO unit to stabilize 2.

“…In previous literature, based on IR data, the product derived from the reaction of stilbene episulfoxide and [RhCl(PPh 3 ) 3 ] was proposed to be the dimer [{RhCl(SO)(PPh 3 )} 2 ], in which the SO ligands were terminal and Cl ligands bridged the Rh centers 20. Compound 6 represents a rare example of a [Rh(SO)] complex6c, 20, 21 and is only the second to be crystallographically characterized 22…”
