Molybdenum and Tungsten Tricarbonyl Complexes with the Tripodal Ligands [nBuSn(2-pyridyl)3] and [RSn(methylthiomethyl)3]
摘要:
The ligands [(BuSn)-Bu-n(2-pyridyl)(3)] and [RSn(methylthiomethyl)(3)] (R = Bu-n, Me) have been prepared in a one-pot, two-step procedure from the corresponding alkyltin trichloride and 2-pyridyl or methylthiomethyl carbanions. The reaction of these ligands with [M(CO)(3)(NCR)(3)] (M = Mo, W) afforded the tricarbonyl compounds [{(BuSn)-Bu-n(2-pyridyl)(3)}M(CO)(3)] and [{RSn(methylthiomethyl)(3)}M(CO)(3)]. In addition to IR and NMR characterization, the structure of three of these new complexes was determined by single-crystal X-ray diffraction.
