H. Schmidt et al., GERMYLENES AND GERMYL CATIONS WITH THE ,4-DI-TERT-BUTYL-6-(N,N-DIMETHYLAMINOMETHYL)PHENYL LIGAND, Organometallics, 17(11), 1998, pp. 2149-2151
The ,4-di-tert-butyl-6-(N,N-dimethylaminomethyl)phenyl (Mamx) ligand a
llows the synthesis of the germylenes MamxGeCl (I), Mamx(2)Ge (2), Mam
x(Tip)Ge (3; Tip = 2,4,6-iPr(3)C(6)H(2)), MamxGeN(3) (4), MamxGeN(SiMe
3)(2) (5), and MamxGe[Fe(CO)(2)Cp] (6), which are all stabilized by c
oordination of the amino side chain. Reactions of 2 and 3 with Mel yie
ld the ionic compounds Mamx(Tip)(Me)Ge+I-(7) and Mamx(2)(Me)Ge+I- (8),
respectively; the X-ray crystal structure of 7 shows a trigonal-plana
r coordination at the Ge center and a nearly perpendicular Ge-N bond.
