摘要：
Treatment of 1H-(3,5-dimethylpyrazol-1-ylmethyl)-1,2,3-benzotriazole [CH2(3,5-Me(2)Pz)(Bt)] with one equivalent of n-BuLi followed by Ph3SnCl gave a ditin derivative [(Ph3Sn)(2)C(3,5-Me(2)Pz)(Bt)]. Use of two equivalents of n-BuLi gave CH2(3,5-Me(2)Pz)(Bt-SnPh3) together with (Ph3Sn)(2)C(3,5-Me(2)Pz)(Bt). Reaction of (Ph3Sn)(2)C(3,5-Me(2)Pz)(Bt) with W(CO)(5)(THF) gave (Ph3Sn)(2)C(3,5-Me(2)Pz)(BtW(CO)(5)), while the reaction of CH2(3,5-Me(2)Pz)(Bt-SnPh3) with W(CO)(5)(THF) resulted in the formation of three complexes, namely CH2(3,5-Me(2)Pz)(Bt-SnPh3)W(CO)(5), CH2(3,5-Me(2)Pz)(Bt-SnPh3)W(CO)(4) and CH2(3,5-Me(2)Pz)(Bt)W(CO)(4). All of these products have been characterized by physicochemical and spectroscopic methods. In addition, the structures of five of the compounds have been confirmed by X-ray structural analyses, revealing that the functionalized 1H-(3,5-dimethylpyrazol-1-ylmethyl)-1,2,3-benzotriazole has variable coordination modes.
