1,2-ジカルバクロソドデカボラン（12）-1,2-ジチオレートキレートリガンド、[（B10H10）C2S2] 2-を含むヘテロメタルクラスター（IR2RH、IR2W、RH3）の合成と特性評価

16電子ハーフサンドイッチ複合体[cp* ir [s2c2（b10h10）]][[cp*ir [s2c2（b10h9）]] rh（cod）]（2）、trans- [cp*ir [s2c2（b10h9）]] rh [s2c2（b10h10）]]]複合3には、2つの異なるIR-RH結合（3.003（3）および2.685（3）のアンストローム）を持つIR2RHバックボーンが含まれています。二核複合体2は単核16電子複合体1aと反応して、還流トルエンに3を与えます。BF3.ETO2の存在下での1Aと[W（CO）3（Py）3]（Py = c5h5n）との反応は、三核クラスター[[cp*ir [s2c2）]] 2w（co）2]（5）と一緒に[[cp*ir（co）] [s2c2（b10h10）] w（co）5（co）w（co）w（co）w（co）5）と一緒に[cp*ir（co）[s2c2（b10h10）]]（7）。[cp*rh [s2c2（b10h10）]]（1 b）を[rh（cod）（mu-cl）] 2]と類似した反応を調査し、2つの複合体Cis- [cp*rh [s2c2（b10h10）]] 2rh]（8）およびtrans- [cp*rh [s2c2（b10h10）] 2rh]還流THF溶液では、シソイド8は95％以上の収率でトランスイド9に変換されます。2〜9はすべて、NMR分光法（1H、11B NMR）によって特徴付けられ、X線回折構造分析は複合体2〜5、8、および9について報告されています。

The 16-electron half-sandwich complex [Cp*Ir[S2C2(B10H10)]] (Cp* = eta5-C5Me5) (1a) reacts with [[Rh(cod)(mu-Cl)]2] (cod = cycloocta-1,5-diene, C8H12) in different molar ratios to give three products, [[Cp*Ir[S2C2(B10H9)]]Rh(cod)] (2), trans-[[Cp*Ir[S2C2(B10H9)]]Rh[[S2C2(B10H10)]IrCp*]] (3), and [Rh2(cod)2[(mu-SH)(mu-SC)(CH)(B10H10)]] (4). Complex 3 contains an Ir2Rh backbone with two different Ir-Rh bonds (3.003(3) and 2.685(3) angstroms). The dinuclear complex 2 reacts with the mononuclear 16-electron complex 1a to give 3 in refluxing toluene. Reaction of 1a with [W(CO)3(py)3] (py = C5H5N) in the presence of BF3.EtO2 leads to the trinuclear cluster [[Cp*Ir[S2C2(B10H10)]]2W(CO)2] (5) together with [[Cp*Ir(CO)[S2C2(B10H10)]]W(CO)5] (6), and [Cp*Ir(CO)[S2C2(B10H10)]] (7). Analogous reactions of [Cp*Rh[S2C2(B10H10)]] (1 b) with [[Rh(cod)(mu-Cl)]2] were investigated and two complexes cis-[[Cp*Rh[S2C2(B10H10)]]2Rh] (8) and trans-[[Cp*Rh[S2C2(B10H10)]]2Rh] (9) were obtained. In refluxing THF solution, the cisoid 8 is converted in more than 95 % yield to the transoid 9. All new complexes 2-9 were characterized by NMR spectroscopy (1H, 11B NMR) and X-ray diffraction structural analyses are reported for complexes 2-5, 8, and 9.
