Preparation, properties, and molecular structures of dimethylaminomethyl ferrocenyl compounds of selected elements of group 13 and 14

Dimethylmetalchlorides of gallium and indium react wi th dime thylaminometh ylferrocenyllithium (FcNLi) to give the corresponding dimethylmetaldimethyl aminomethylferrocenes 1 and 2 [Me(2)MFcN; M=Ga, In]. In a similar manner di alkylmetaldichlorides of germanium and tin yield the expected chlordialkylm etaldimethylaminomethylferrocenes 3-5 [R-2(Cl)MFcN; M=Ge; R=Me(3), M=Sn; R= Me (4), Ph (5)]. In a reaction of Me3Al and Me2AlCl with dimethylaminomethy lferrocene the formation of the 1 : 1 adducts 7 and 8 could be observed. Al l compounds were characterised by H-1 and C-13 nmr spectroscopy. The molecu lar structures of 1, 3, 4 and 7 were determined. 3 and 4 build in contrast to 1 monomeric molecules with chelat rings as a result of the M-N coordinat ion. Compound 7 consist of monomeric molecules with 4 coordinated Al atoms.
