ABSTRACT
The clusters TiO(OPr)(OMc)(OPR) (OMc = methacrylate; R = Et, CHCHCHBr) and Ti(OPr)(OMc)(OPCHCH=CH) were obtained when Ti(OPr) was reacted with the corresponding bis(trimethylsilyl) phosphonate and methacrylic acid. Oxo clusters of the composition TiO(OPr)(OMc)(OPR), with a variety of groups R (Et, Ph, CH=CH, CHPh, CHCH=CH, CHCHCHBr, CHCHCN, CHC(O)Me, CHCHOC(O)C(Me)=CH), were formed instead, when a stoichiometric amount of water was added to the reaction mixture.
摘要
当Ti(OPr)与相应的双(三甲基甲硅烷基)膦酸酯和甲基丙烯酸反应时，得到了簇合物TiO(OPr)(OMc)(OPR)（OMc = 甲基丙烯酸酯；R = 乙基、CHCHCHBr）和Ti(OPr)(OMc)(OPCHCH=CH)。相反，当向反应混合物中加入化学计量的水时，会形成组成TiO(OPr)(OMc)(OPR)的氧簇，其中R有多种基团（乙基、苯基、CH=CH、CHPh、CHCH=CH、CHCHCHBr、CHCHCN、CHC(O)Me、CHCHOC(O)C(Me)=CH）。
