1,2-N,N-DIMETHYLAMINOMETHYLFERROCENYL AS A LIGAND TOWARDS SILICON

The reinvestigation of reactions of [2-(dimethylaminomethyl)ferrocenyl ]lithium (1), (FcN)Li, with silicontetrachloride respectively, chlorot rimethylsilane delivers new analytical data for (FcN)SiCl3 (2) and (Fc N)SiMe3 (3), especially the structure of 2 has been subjected to X-ray structure analyses. The reaction of 2 with sodiumisopropylate yields the novel (FcN)Si(O-(C3H7)-C-i)(3) (4) which was subjected to X-ray di ffraction analysis by its hydrochloride (FcN)Si(O-(C3H7)-C-i)(3) x HCl (5). The reaction of 1 with 1,6-dichlorododecamethylhexasilane yields the novel (FcN)(SiMe2)(6)(FcN) (6). (C) 1998 Elsevier Science S.A. Al l rights reserved.
