The following new amidinate-substituted boron halides are reported: [PhC{N(SiMe3)}2]BCl2 (6), [MeC{NCy} 2]BCl2 (10), [Mes*C{NCy}2]BCl2 (11), [MeC{NiPr}2]BCl2 (12), and [FcC{NCy}2]BBr2 (13). Compound 6 was prepared via the trimethylsilyl chloride elimination reaction of BCl3 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 BX3. Compound 13 was prepared via the insertion of 1,3-dicyclohexylcarbodiimide into the B-C bond of ferrocenyldibromoborane FcBBr2. The molecular structures of 6, 10, 11, 13 and the known compound [PhC{N(SiMe3)}2]BBr2 (1) were established by single-crystal X-ray diffraction.
