“…The six-membered ring containing a {C2BS3} moiety adopts a boat conformation, similar to the reported diborinanes, such as bis(cAAC)-stabilized 3,6-dicyano-1,2,4,5-tetrasulfa-3,6-diborinane reported by Braunschweig et al where the central {B2S4} ring displayed a boat conformation and was the first example of a structurally and NMR-spectroscopically characterized {B2S4}-heterocycle [75]. Meller et al reported the synthesis and characterization of a diborinane-tungsten adduct, [(BMe)2(NH){N(SiMe3)}2(S){W(CO)5}] [76]. In contrast, the structurally characterized dioxaborinane, [CN(C6H5)(BO2C3H5)(C6H4)(C4H9)], adopted the half-chair conformation [77].…”

The thermolysis of arachno-1 [(Cp*Ru)2(B3H8)(CS2H)] in the presence of tellurium powder yielded a series of ruthenium trithia-borinane complexes: [(Cp*Ru)2(η1-S)(η1-CS){(CH2)2S3BH}] 2, [(Cp*Ru)2(η1-S)(η1-CS){(CH2)2S3B(SMe)}] 3, and [(Cp*Ru)2(η1-S)(η1-CS){(CH2)2S3BH}] 4. Compounds 2–4 were considered as ruthenium trithia-borinane complexes, where the central six-membered ring {C2BS3} adopted a boat conformation. Compounds 2–4 were similar to our recently reported ruthenium diborinane complex [(Cp*Ru){(η2-SCHS)CH2S2(BH2)2}]. Unlike diborinane, where the central six-membered ring {CB2S3} adopted a chair conformation, compounds 2–4 adopted a boat conformation. In an attempt to convert arachno-1 into a closo or nido cluster, we pyrolyzed it in toluene. Interestingly, the reaction led to the isolation of a capped butterfly cluster, [(Cp*Ru)2(B3H5)(CS2H2)] 5. All the compounds were characterized by 1H, 11B{1H}, and 13C{1H} NMR spectroscopy and mass spectrometry. The molecular structures of complexes 2, 3, and 5 were also determined by single-crystal X-ray diffraction analysis.

Mononuclear carbonylmetal complexes of chromium, molybdenum and tungsten containing the sulfane S(C7H7)2 (1) have been obtained starting from precursors such as the THF‐stabilized pentacarbonylmetal fragments, [M(CO)5](thf), the acetonitrile intermediates M(CO)6‐x(CH3CN)x (x = 1, 2, 3) (M = Cr, Mo, W) or the η4‐norbornadiene complexes M(CO)4(C7H8) (M = Cr, Mo). In addition to the pentacarbonyls, M(CO)5[S(C7H7)2] (M = Cr (2a), Mo (2b), W (2c)) which contain 1 unchanged as a two‐electron sulfane ligand with two pending cyclohepta‐2, 4, 6‐trienyl substituents, isomeric complexes M(CO)5[S(CH2Ph)(C7H7)] (M = Cr (3a), W (3c)) were obtained at higher temperatures (40‐50 °C) in which one of the two organic groups has been transformed into a benzyl substituent. In the tetracarbonyls, cis‐M(CO)4[S(C7H7)(η2‐C7H7)] (M = Mo (4b), W (4c)), the ligand 1 serves as an olefinic sulfane four‐electron chelate ligand. The reaction of either Mo(CO)6 or (mesitylene)Mo(CO)3 with S(C7H7)2 (1) in boiling THF leads to the sulfur‐free ditropyl complex Mo(CO)3[(η6‐C7H7)‐C7H7] (5b, two isomers). The 1H and 13C NMR spectra of the new complexes 2‐4 reveal various dynamic processes including pyramidal inversion of the sulfur atom and [1, 7]‐sigmatropic shifts at the C7H7 ring. The molecular structures of 2c, 3a, 4b and 4c have been determined by X‐ray crystallography.
