Abstract

Six boron compounds have been synthesized through the combination of phenylboronic acid and various Salen (N,N′-ethylenebis(2-hydroxy)benzylidenimine) ligands. They contain seven- and eight-membered heterocycles with a bridging oxygen and have the formula: L[(PhB)₂(μ-O)] (L= Acmen (1), Salen(^tBu) (2), Sal(2-OH)pen (3), Salpen(^tBu) (4), Acpen (5) and L[B₂(μ-O)(O₂BPh)] (L = Acen (6), Salmen (7)). Compounds 6 and 7 are interesting trinuclear boron derivatives with two four-coordinate and one three-coordinate boron atoms. The compounds have been characterized by MP, MS, IR, EA and ¹H- and ¹¹B-NMR, by ¹¹B-MAS for 6 and 7 and by X-ray crystallography for 2, 4-7.
