Abstract

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(trmiethylsilyl)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. © The Royal Society of Chemistry 2005.
