The synthesis of 10-halo-substituted derivatives of nido-7,8,9-PC2B8H11 and [nido-7,8,9-PC2B8H10]- and new linear correlations between NMR parameters
Original language description
Halogenation of the eleven-vertex phosphadicarbaborane nido-7,8,9-PC2B8H10 (1) with CCl4, Br2 or I2 in the presence of anhydrous AlCl3 (solvents CCl4, CS2, and benzene, respectively) generated a series of 10-X-nido-7,8,9-PC2B8H10 (10-X-1) compounds (X =Cl, Br, and I) in yields 55, 65, and 63%, respectively. Anionic compounds [10-X-nido-7,8,9-PC2B8H10]- (10-X-2) (X = Cl, Br, I) were obtained by treatment of the corresponding neutral compounds with "proton sponge" (PS = 1,8-bis(dimethylamino)naphthalene). Interesting halo-substitution NMR effects are also discussed in terms of new linear correlations. All the changes in NMR chemical shifts (D) induced at the various skeletal sites by halogeno substituents on specific sites can be related to an arbitraryreference skeleton and are, within experimental errors, linearly proportional to those induced at the substituted site (Da) of the reference skeleton.

Syntéza 10-halogensubstituovaných derivátů nido-7,8,9-PC2B8H11 a [nido-7,8,9-PC2B8H10]- a nové lineární korelace mezi NMR parametry
Czech description
Halogenační reakce nido-7,8,9-PC2B8H11 vedly k isolaci halogenderivátů 10-X-nido-7,8,9-PC2B8H10 (X = Cl, Br, I), jejichž reakce s ?protonovou houbou? (1,8-bis-(dimethylaminonaftalen)) vede ke vzniku aniontů obecné konstituce [10-X-nido-7,8,9-PC2B8H9]-. Na těchto sloučeninách byly demonstrovány nové lineární korelace mezi chemickými posuny na substituovaném B-atomu a podobnými charakteristikami jiných boranových skeletů.
