Unsymmetrically substituted dimethyldiaminosilanes of the general formula SiMe2(NR2)(NR′2) have been prepared by treating LiNR2 with SiMe2Cl(NR′2) (NR2, NR′2 = NMe2, NC4H8, NHiPr, NHtBu, NHCH2CH2NMe2 or NHCH2CH2OMe). Their ligating properties towards zirconium(IV) have been investigated as a function of the nitrogen substituents and the syntheses of the binary compound Zr[SiMe2(NiPr)(NtBu)]2 and of
通式 SiMe2(NR2)(NR'2) 的不对称取代二甲基二氨基硅烷已通过用 SiMe2Cl(NR'2)(NR2、NR'2 = NMe2、NC4H8、NHiPr、NHtBu、NHCH2CH2NMe2 或 NHCH2CH2OMe)处理 LiNR2 制备。已经研究了它们对锆 (IV) 的连接性能与氮取代基和二元化合物 Zr[SiMe2(NiPr)(NtBu)]2 和锆衍生物 ZrX3(L) [X = Cl, NMe2; L = SiMe(NR)(NR′2),NR = NiPr、NtBu、NCH2CH2NMe2、NCH2CH2OMe;NR'2 = NMe2, NC4H8, NHiPr, NHtBu] 也有报道。化合物的溶液结构和动力学已通过一维/二维多核核磁共振波谱阐明。(© Wiley-VCH Verlag GmbH & Co.
