چکیده
An ortho-rhom-bic polymorph of the title compound, [Fe(C(5)H(5))(C(8)H(17)B(10)O)] or C(13)H(22)B(10)FeO, is described here in addition to the known monoclinic polymorph [Crundwell et al. (1999 ▶). Acta Cryst.C55, IUC9900087]. The asymmetric unit contains four independent mol-ecules with C(cage)-C(cage) distances of 1.636 (16)-1.700 (16) Å, and with the methyl-hydr-oxy groups disordered over two positions in each mol-ecule [occupancy ratios 0.80 (2):0.20 (2), 0.59 (3):0.41 (3), 0.60 (2):0.40 (2) and 0.793 (17):0.207 (17)].

1,2-Bis(methylsulfanyl)-1,2-dicarba-closo-dodecaborane(12).
In the title compound, 1,2-(SCH3)2-1,2-closo-C2B10H10 or C4H16B10S2, the methylsulfanyl groups are bonded to the C atoms of the 1,2-dicarba-closo-dodecaborane cage. The Ccage-Ccage distance is 1.8033 (18) A and the S-Ccage-Ccage-S torsion angle is 1.07 (13) degrees. The Ccage-Ccage distance is compared with those in other 1,2-dicarba-closo-dodecaborane derivatives.

Experimental data on the mutual rearrangements of isomeric dicarba-closododecaboranes(12) and their B-halogen derivatives are reviewed. Reactions involving electron transfer to dicarba-closo-dodecaboranes(12), and the properties of the resulting dodecahydrodicarba-nido-dodecaborates(2 —) as intermediates of the rearrangements of 1.7and 1,12-dicarba-closo-dodecaboranes(12) are discussed.

The reaction of 1,2-bis(N,N-dimethylaminochloro-phosphanyl)-1,2-dicarba-closo-dodecaborane(12) and lithiated phenylacetylene gives a five-membered dihydrophosphole derivative with an exocyclic phosphanyl group. This unexpected reaction opens new possibilities for the synthesis of carbaborane-containing phosphorus heterocycles. P,P'-alkynylated 1,2-bis(phosphanyl)-1,2-dicarba-closo-dodecaborane(...

Two C-dimesitylboryl-1,2-dicarba-closo-dodecaboranes, 1-(BMes2)-2-R-1,2-C2B10H10 (1, R = H, 2, R = Ph), were synthesised by lithiation of 1,2-dicarba-closo-dodecaborane and 1-phenyl-1,2-dicarba-closo-dodecaborane, respectively, with n-butyllithium and subsequent reaction with fluorodimesitylborane. These novel compounds were structurally characterised by X-ray crystallography. Compounds 1 and 2...
متن کاملDicarba-closo-dodecaborane(12) derivatives of phosphonium salts: easy formation of nido-carborane phosphonium zwitterions.
The first examples of arylphosphonium salts containing a dicarba-closo-dodecaborane(12) (closo-carborane) are reported; in contrast to the 1,12-carborane derivative, the 1,2- and 1,7-isomers undergo a facile deboronation reaction in polar solvents to afford the corresponding nido-carborane phosphonium zwitterions.
