Abstract: | Metal Complexes with Anionic Ligands of Elements of the Main Group IV. VII(1) Substitution Reactions of Carbonylnitrosyl and Nitrosyltrifluorophosphine Transition Metal Complexes with Trichlorostannid L-substitution by SnCl3]? occurs if the nitrosyl complexes Co(NO)L3 and Fe(NO)2L2 (L = CO or PF3) are reacted with N(C2H5)4]SnCl3] thermically in tetrahydrofuran as well as photochemically induced in methylenechloride. The complexes Co(NO)L3 yield the mono-substitution products N(C2H5)4]Co(NO)L2SnCl3], with the iron compounds Fe(NO)2L2 only the disubstituted derivative N(C2H5)4]2Fe(NO)2(SnCl3)2] can be isolated. On the other hand CO substitution at (π-C5H5)Mo(NO)(CO)2 by UV irradiation did not suceed both with SnCl3]? and with PF3. From the IR-spectroscopic data a leastly with PCl3 comparable π-acceptor ability is derived for the trichlorostannido ligand. |
