摘要：

Reaction of 2-salicylideneamino hydroxyethane (H(2)SAE) with B(NMe2)(3), B(OH)(3) and C6F5B(OH)(2) leads to the dimeric boron compounds [B(SAE)(NMe2)](2) (2), [B(SAE)(OH)](2) (3) and [B(SAE)(C6F5)](2) (4) in moderate to good yields. Compound 2 hydrolyses slowly at room temperature (r.t.) to give the dimeric ore-bridged boron compound mu -oxo-[B(SAE)](2) (5). Dehydration of 3 or hydrolysis of 4 with elimination of the aryl group conduced to the same derivative. The X-ray crystallographic analysis confirmed the molecular structure for compound 5.
