The cationic terminal borylene complex [(eta5-C5H5)(CO)2FeB(eta5-C5Me5)][AlCl4] has been isolated from the reaction of [(eta5-C5H5)(CO)2FeB(Cl)(eta1-C5Me5)] with AlCl3 and on the basis of X-ray crystallographic data, spectroscopic data and a DFT calculation it is concluded that the B-->Fe bond order is one.
A 1 : 1 Lewis acid-base complex between CyN=C=NCy and PhBCl2 has been isolated and structurally characterized, heating of which in refluxing toluene results in the amidinate, [PhC{NCy}2]BCl2; the overall reaction has been modeled by DFT calculations.
The following new amidinate-substituted boron halides are reported: [PhC{N(SiMe(3))}(2)]BCl(2)(6), [MeC{NCy}(2)]BCl(2)(10), [Mes*C{NCy}(2)]BCl(2)(11), [MeC{N(i)Pr}(2)]BCl(2)(12), and [FcC{NCy}(2)]BBr(2)(13). Compound 6 was prepared via the trimethylsilyl chloride elimination reaction of BCl(3) with N,N,N'-tris(trimethylsilyl)benzamidine, and compounds 10-12 were prepared by salt metathesis between the lithium amidinates [RC(NR')(2)]Li and BX(3). Compound 13 was prepared via the insertion of 1,3-dicyclohexylcarbodiimide into the B-C bond of ferrocenyldibromoborane FcBBr(2). The molecular structures of 6, 10, 11, 13 and the known compound [PhC{N(SiMe(3))}(2)]BBr(2)(1) were established by single-crystal X-ray diffraction.
