The oxometal complexes [MoO2(η2-O-NR2)2], R = Et or CH2Ph, reacted with the strong Lewis acid B(C6F5)3 at their oxo functionality to give cis-[MoOOB(C6F5)3}(η2-ONR2)2], (R = Et 1 or CH2Ph 2). Reaction of the peroxo complex [MoO(O2)η2-PhN(O)C(O)Ph}2] with the same Lewis acid led initially to the formation of [MoO(O2)B(C6F5)3}η2-PhN(O)C(O)Ph}2] 3, which decomposes to form [MoOOB(C6F5)3}η2-PhN(O)C(O)Ph}2] 4. Compounds 1 and 4 have been characterised by X-ray crystallography.
氧化金属配合物 [MoO2(δ-2-O-NR2)2](RÂ = Â Et 或 CH2Ph)与强
路易斯酸 B(
C6F5)3 在其氧官能团处发生反应,生成顺式 [MoOOB( )3}(δ-2-ONR2)2](RÂ = Â Et 1 或 CH2Ph 2)。过氧配合物[MoO(O2)δ-2-PhN(O)C(O)Ph}2]与相同的
路易斯酸反应,首先形成[MoO(O2)B( )3}δ-2-PhN(O)C(O)Ph}2] 3,然后分解形成[MoOOB( )3}δ-2-PhN(O)C(O)Ph}2] 4。化合物 1 和 4 已通过 X 射线晶体学鉴定。
