Alternative syntheses and X-ray diffraction analyses of the parent tricarbaborane compounds [nido-7,8,9-C3B8H11]−, [nido-7,8,10-C3B8H11]− and [1-(η5-C5H5)-closo-1,2,4,10-FeC3B8H11] by Josef Holub; Aleš Růžička; Zdeňka Padělková; Bohumil Štíbr is a Chemistry article available to read on EtoBox.

What is Alternative syntheses and X-ray diffraction analyses of the parent tricarbaborane compounds [nido-7,8,9-C3B8H11]−, [nido-7,8,10-C3B8H11]− and [1-(η5-C5H5)-closo-1,2,4,10-FeC3B8H11] about?

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 þ salt of the [nido-7,8,9-C 3 B 8 H 11 ] À anion (2). This was converted into PSH þ and Me 4 N þ salts via metathetic cation exchange. Heating of the solid Me 4 N þ [7,8,9-C 3 B 8 H 11 ] À in mineral oil at 350 C for 2 h resulted in thermal rearrangement and isolation of the cage isomeric compound Me 4 N þ [7,8,10-C 3 B 8 H 11 ] À . Finally, compound 1 was directly complexed via reaction with [CpFe(CO) 2 ] 2 (Cp 1⁄4 h 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 generic compounds of tricarbollide chemistry, 1 (PSH þ salt), 2 (MePPh 3 þ salt), and 4, were established unambiguously by an X-ray diffraction analysis.
