Aluminum Amides Derived from Metalation of N,N'-Bis(trimethylsilyl)ethylenediamine.
The reaction of N,N'-bis(trimethylsilyl)ethylenediamine with H(3)Al.NMe(3) gives products based on metalation (H(2) elimination), [{[CH(2)N(SiMe(3))](2)AlH}(2)] (1) and [{CH(2)N(SiMe(3))}(2)AlN(SiMe(3))CH(2)CH(2)N(H)SiMe(3)] (2), as well as products derived from N-Si bond cleavage and metalation, [{[CH(2)N(SiMe(3))](2)AlH}(2){HAlN(SiMe(3))CH(2)CH(2)NAlH(2)}] (4) and [H(2)Al{CH(2)N(SiMe(3))}(2)AlN(SiMe(3))CH(2)CH(2)NAl(H)(2).NMe(3)}] (5). Similarly, [Me(3)SiN(H)CH(2)CH(2)N(SiMe(3))AlCl(2)] (3) was isolated as the redistributed/metalated product from the reaction of the same diamine with H(2)Al(Cl).NMe(3). The following crystal data were obtained: (1) monoclinic, space group P2(1)/c (No. 14), a = 13.636(4) Å, b = 9.565(3) Å, c = 22.683(4) Å, beta = 105.67(2) degrees, 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, beta = 100.36(1) degrees, Z = 8; (3) triclinic, space group P&onemacr; (No. 2), a = 11.762(3) Å, b = 11.927(3) Å, c = 7.288(2) Å, alpha = 107.46(2) degrees, beta = 95.29(2) degrees, gamma = 110.41(2) degrees, Z = 2; (4) triclinic, space group P&onemacr; (No. 2), a = 13.884(4) Å, b = 15.379(4) Å, c = 11.044(2) Å, alpha = 102.11(2) degrees, beta = 103.85(2) degrees, gamma = 109.28(2) degrees, Z = 2; (5) triclinic, space group P&onemacr; (No. 2), a = 10.925(5) Å, b = 11.060(5) Å, c = 12.726(4) Å, alpha = 92.38(3) degrees, beta = 95.67(2) degrees, gamma = 96.90(2) degrees, Z = 2.
