摘要：

The complexes [Mo(NO){HB(impz)(3)}I(ER)] [impz = isopropylmethylpyrazol-1-yl; E = O; R = Pr-i, Bu(t), CH(2)SiMe(3), (CH2)(4)I, Ph or C(6)H(4)Me-4: E = NH; R = Ph or C(6)H(4)Me-4] have been prepared from a mixture. of isomers of [Mo(NO){HB(impz)(3)}I-2]; in the cases where ER = OPh, O(CH2)(4)I or OCH(2)SiMe(3) the products could only be obtained as mixtures of isomers, but where ER = OPri, OBu(t), NHPh or NHC(6)H(4)Me-4 the products could be thermally converted into compounds containing a single isomer of the ligand HB(impz)(3). Reactions involving REH (E = O; R = Me, Pr-i or Bu(t); E = NH; R = Et, CH(2)Ph or Ph) and a single isomer of [Mo(NO){HB(impz)(3)}I-2] produced [Mo(NO){HB(impz)(3)}I(ER)] containing a single isomer of the ligand HB(impz)(3) and which did not rearrange on heating. The locations of the methyl and isopropyl groups in the HB(impz)(3) ligand in [Mo(NO){HB(3-Pr-i-5-Me-C3N2H)(3)}(OPri)(2)] have been determined by X-ray crystallographic methods.
