| Abstract
| - The reaction ofN,N‘-bis(trimethylsilyl)ethylenediamine withH3Al·NMe3 gives products based onmetalation (H2elimination),[{[CH2N(SiMe3)]2AlH}2](1) and[{CH2N(SiMe3)}2AlN(SiMe3)CH2CH2N(H)SiMe3](2), as well asproducts derived from N−Si bond cleavage and metalation,[{[CH2N(SiMe3)]2AlH}2{HAlN(SiMe3)CH2CH2NAlH2}] (4) and[H2Al{CH2N(SiMe3)}2AlN(SiMe3)CH2CH2NAl(H)2·NMe3}](5). Similarly,[Me3SiN(H)CH2CH2N(SiMe3)AlCl2](3) was isolated as the redistributed/metalated product fromthe reaction of the same diaminewith H2Al(Cl)·NMe3. Thefollowing crystal data were obtained: (1) monoclinic,space group P21/c (No. 14),a= 13.636(4) Å, b = 9.565(3) Å, c= 22.683(4) Å, β = 105.67(2)°, Z = 4;(2) monoclinic, space group C2/c(No.15), a = 31.887(3) Å, b =10.145(6) Å, c = 17.718(3) Å, β =100.36(1)°, Z = 8; (3) triclinic, spacegroup P1̄(No. 2), a = 11.762(3) Å, b =11.927(3) Å, c = 7.288(2) Å, α =107.46(2)°, β = 95.29(2)°, γ = 110.41(2)°,Z= 2; (4) triclinic, space group P1̄ (No.2), a = 13.884(4) Å, b = 15.379(4)Å, c = 11.044(2) Å, α =102.11(2)°,β = 103.85(2)°, γ = 109.28(2)°, Z =2; (5) triclinic, space group P1̄ (No. 2),a = 10.925(5) Å, b =11.060(5)Å, c = 12.726(4) Å, α = 92.38(3)°, β= 95.67(2)°, γ = 96.90(2)°, Z =2.
- The reaction ofN,N‘-bis(trimethylsilyl)ethylenediamine withH3Al·NMe3 gives products based onmetalation (H2 elimination),[{[CH2N(SiMe3)]2AlH}2]and[{CH2N(SiMe3)}2AlN(SiMe3)CH2CH2N(H)SiMe3],as well as products derived from N−Si bond cleavage and metalation,4 and 5 (R = SiMe3). Therelated compound[Me3SiN(H)CH2CH2N(SiMe3)AlCl2]was isolated as the redistributed metalated product from the reactionof the same diamine withH2Al(Cl)·NMe3.
