Syntheses and Characterization of 1-Haloazagermatranes

Abstract: Germanium, Azagermatranes The reaction of tris(dimethylamino)halogermanes, (Me?N)3GeHal (7, Hal = Cl; 8 , Hal = Br), with tris(2-aminoethyl)amines, N(CH2CH2NHR)3 (5, R = H; 6 , R = Me), yield l-halo-N,N',N"-azagermatranes (1, X = Cl, R = H; 2, X = Br, R = H; 3, X = Cl, R = Me; 4, X = Br, R = Me). Treatment of 4 with n-butyllithium affords l-n-butyl-N,N',N"-trimethylazagermatrane (14) in high yield. Reactions of n-BuLi with 7 or (Me2N)4Ge (13) lead to the formation of (Me2N)3Ge-n-Bu (15). On treatment of 15 wit… Show more

“…1 H NMR, 13 C NMR and EI MS data were consistent with those already reported. [13] 1-Chloro-N,NЈ,NЈЈ-tris(trimethylsilyl)azagermatrane (3): A 1.6  nBuLi solution in hexane (4.67 mL, 7.5 mmol) at room temperature was added dropwise to a stirred solution of TMS 3 -tren (0.90 g, 2.5 mmol) in 40 mL of toluene. The reaction mixture was stirred for 5 h and a solution of GeCl 4 (0.53 g, 2.5 mmol) in 10 mL of toluene was added dropwise at room temperature.…”

“…[16,21] We prepared azagermatranes 1 and 2 by transamination reactions of HalGe(NMe 2 ) 3 with Me 3 -tren. [13] Another method for building the main group element azatrane framework was previously only used for transition metals. [22] Tetrahalides (Hal ϭ Cl, Br) of germanium and tin react readily with the trilithium salts of Me 3 -tren and TMS 3 -tren (in toluene at room temperature) to give 1-haloazametallatranes 1Ϫ8 in high yield (Scheme 2).…”
