Unsymmetrically substituted dimethyldiaminosilanes as ligands towards zirconium(IV)
Passarelli, Vincenzo,Zanella, Pierino
, p. 4439 - 4446 (2004)
Unsymmetrically substituted dimethyldiaminosilanes of the general formula SiMe2(NR2) (NR′2) have been prepared by treating LiNR2 with SiMe2C1(NR′2) (NR2, NR′2 = NMe2, NC4H 8, NHiPr, NHtBu, NHCH2CH2NMe2 or NHCH2CH2-OMe). 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)(NiBu)] 2 and of the zirconium derivatives ZrX3(L) [X = Cl, NMe2; L = SiMe(NR) (NR′2), NR = NiPr, NtBu, NCH 2CH2NMe2, NCH2CH2OMe; NR′2 = NMe2, NC4H8, NHiPr, NHtBu] are also reported. The solution structures and dynamics of the compounds have been elucidated by 1D/2D multinuclear NMR spectroscopy. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.

Paragraph 0075, (2018/10/03)
PROBLEM TO BE SOLVED: To provide a group 4 metal complex having excellent thermal stability and proper vapor pressure and suitable as a material for preparing a group 4 metal-containing thin film. SOLUTION: There is provided the group 4 metal complex represented by the general formula (1), where M represents a group 4 metal atom, R1, R2, R3 and R4 each represent independently a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, R5, R6 and R7 each represent independently an alkyl group having 1 to 8 carbon atoms, R8, R9 and R10 each represent independently an alkyl group having 1 to 6 carbon atoms or a di (alkyl having 1 to 3 carbon atoms) amino group.

Chloraminosilanes II. Preparation and spectroscopic studies on alkyl-(dimethylamino)chlorosilanes
Washburne,Peterson Jr.
, p. 59 - 64 (2007/10/12)
Several new compounds containing both chloro and dimethylamino groups linked to silicon have been prepared. The general method involved reacting a solution of the appropriate polychlorosilane in ether at ca. - 50° with a chilled ethereal solution of dimethylamine. Prepared in this fashion were CH3Si(NMe2)Cl2, CH3Si(NMe2)2-Cl, PhSi(NMe2)Cl2, PhSi(NMe2)2Cl, CH3(H)Si(NMe2)Cl, (CH3)2Si(NMe2)Cl, CH2CH(CH3)Si(NMe2)Cl, and Ph2Si(NMe2)Cl. Comparison of the spectra of these compounds with those in the perhalo and peramine series showed that replacement of NMe2 for Cl resulted in an upfield shift of the resonances of the other groups linked to silicon, a shift which parallels that observed upon substitution of CH3 for Cl. The relationship of ν(SiH) in the IR and δ(SiH) in the NMR spectra was linear.
