Abstract

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.
