  A study of ortho- and para-siloxyanilines for the synthesis of mono-, bi-, and tetra-nuclear early transition metal–imido complexes

  摘要：

  The siloxyanilines o-Me(3)SiOC(6)H(4)NH(2) (1) and p-RMe(2)SiOC(6)H(4)NH(2) (R = H (2); R = Me (3)), and their N-silylated derivatives p-Me(3)SiOC(6)H(4)NHSiMe(3) (4) and p-Me(3)SiOC(6)H(4)N(SiMe(3))(2) (5) have been prepared from ortho- or para-aminophenol and used in the synthesis of imido complexes. Thus, binuclear [{Ti(eta (5)-C(5)H(5))Cl} {mu -NC(6)H(4)(p-OSiMe(3))}](2) (6) and mononuclear [TiCl(2){NC(6)H(4)(p-OSiMe(3))}(py)(3)] (7) imido complexes have been obtained from the reaction of 3 and [Ti(eta (5)-C(5)H(5))Cl(3)] or [TiCl(2)(N'Bu)(py)(3)], respectively. In contrast, the reaction of 1 with TiCl(4) and 'Bupy affords the titanocycle [TiCl(2){OC(6)H(4)(o-NH)-N,O}('Bupy)(2)] (8). Compound 5 has also been used to prepare the niobium imide complex [NbCl(3){NC(6)H(4)(p-OSiMe(3))}(MeCN)(2)] (9), by its reaction with NbCl(5) in CH(3)CN. These findings have been applied to the synthesis of polynuclear systems. Thus, chlorocarbosilane Si[CH(2)CH(2)CH(2)Si(Me)(2)Cl], (CS-Cl) has been functionalized with the ortho- and para-aminophenoxy groups to give 10 and 11, respectively. The use of 11 has allowed the formation of the tetranuclear compound 12. Attempts to synthesize terminal imido titanium complexes from 10 and TiCl(4) in the presence of 'Bupy and Et(3)N, give complex 8 and carbosilane CS-Cl. (C) 2000 Elsevier Science S.A.

  Infinite dilution (29)Si and (13)C NMR chemical shifts were determined from concentration dependencies of the shifts in dilute chloroform and acetone solutions of para substituted O-silylated phenols, 4-R-C6 H4 -O-SiR'2 R'' (R = Me, MeO, H, F, Cl, NMe2, NH2, and CF3), where the silyl part included groups of different sizes: dimethylsilyl (R' = Me, R'' = H), trimethylsilyl (R' = R'' = Me), tert-butyldimethylsilyl

  根据对位取代的O-甲硅烷基化苯酚，4-R-C6 H4 -O-SiR'2 R'的稀氯仿和丙酮溶液中的位移的浓度依赖性，可以确定无限稀释的（29）Si和（13）C NMR化学位移。 '（R = Me，MeO，H，F，Cl，NMe2，NH2和CF3），其中甲硅烷基部分包括不同大小的基团：二甲基甲硅烷基（R'= Me，R''= H），三甲基甲硅烷基（R' ＝ R″ ＝ Me），叔丁基二甲基甲硅烷基（R′＝ Me，R″ ＝ CMe3）和叔丁基二苯基甲硅烷基（R′＝ C6H5，R″ ＝ CMe3）。讨论了硅和C-1碳化学位移对Hammett取代基常数的依赖性。结果表明，这些化学位移的取代基敏感性通过与氯仿的结合而降低，
