Alternative syntheses and X-ray diffraction analyses of the parent tricarbaborane compounds [nido-7,8,9-C(3)B(8)H(11)](-), [nido-7,8,10-C(3)B(8)H(11)](-) and [1-(eta(5)-C(5)H(5))-closo-1,2,4,10-FeC(3)B(8)H(11)]
Original language description
Reaction of the neutral tricarbaborane nido-7,8,9-C(3)B(8)H(12) (1) with triethylamine in CH(2)Cl(2) led to quantitative deprotonation and isolation of the corresponding Et(3)NH(+) salt of the [nido-7,8,9-C(3)B(8)H(11)](-) anion (2). This was converted into PSH(+) and Me(4)N(+) salts via metathetic cation exchange. Heating of the solid Me(4)N(+)[7,8,9-C(3)B(8)H(11)](-) in mineral oil at 350 degrees C for 2 h resulted in thermal rearrangement and isolation of the cage isomeric compound Me(4)N(+)[7,8,10-C(3)B(8)H(11)](-). Finally, compound 1 was directly complexed via reaction with [CpFe(CO)(2)](2) (Cp = eta(5)-C(5)H(5)) to generate the ferratricarbollide sandwich [1-Cp-closo-1,2,4, 10-FeC(3)B(8)H(11)] (4) in 60% yield. The structures of all the genericcompounds of tricarbollide chemistry, 1 (PSH(+) salt), 2 (MePPh(3)(+)salt), and 4, were established unambiguously by an X-ray diffraction analysis.
