Abstract

Chromium tricarbonyl complexes of mono-, bis- and tris-(hydroxymethyl) substituted benzene have been prepared via direct thermolysis of the alcohol and chromium hexacarbonyl in dibutyl ether-THF. Conversion into the corresponding benzyl halide complexes has been carried out using either PBr3, HBr (aq), HBr in glacial acetic acid or BX3 (X=Cl, Br or I). A comparative study showed that PBr3 and BBr3 give similar yields and purity and are superior to HBr. Crystallographic studies have been carried out on three benzyl alcohol complexes [Cr{eta(6)-C6H4(CH2OH)(2)-1,4}(CO)(3)], [Cr{eta(6)-C6Me4(CH2OH)(2)-1,4}(CO)(3)] and [Cr{eta(6)-C6H3(CH2OH)(3)-1,3,5}(CO)(3)] and on two benzyl bromide complexes [Cr(eta(6)-C6H5CH2Br)(CO)(3)] and [Cr{eta(6)-C6H4(CH2Br)(2)-1,4}(CO)(3)].
