Abstract: | Various Salen ligands (Salen(
t
Bu)H2=N, N -ethylenebis(3,5-di-tertbutyl(2-hydroxy)benzylidenimine) were used to prepare borosilyl and -O bridged borosilyl compounds having the formula, L{B(OSiMe3)2}2 (L=Salen(
t
Bu) (1), Salpen(
t
Bu) (2), Salben(
t
Bu) (3), Salhen(
t
Bu) (4) and L(BOSiMe3)2( -O) (L=Salen(
t
Bu) (5) and Salben(
t
Bu) (6)). In the case of 5 and 6 the formation of the B–O–B linkage takes precedence over the formation of a B–O–Si linkage. All of the compounds were characterized by Mp, elemental analysis, 1H and 11B NMR, IR, MS and in the case of 1, 2, and6 by X-ray crystallography. |
