✦ Synopsis

Telechelic aromatic diamines (1 1) containing an oligo-or polysiloxane chain were prepared in a 4-step synthesis. In the first step 1 -allyloxy-4-nitrobenzene (6) was synthesized and subsequently hydrosilylated with chlorodimethylsilane. In the third step the product (7) was hydrolyzed or condensed with a-hydro-w-hydroxyoligo-or polydimethylsiloxane (9a or 9 b). In the last step the nitro groups were reduced into amino groups. The steps were controlled by means of ' H and 29Si NMR spectroscopy.
