  Dichloro(indol-1-yl)silanes react with lithium-tert.-butylamide to mono- and bis(amino)-(indol-1-yl)silanes 1-3. In addition to this dichlorobis(pyrrol-1-yl)silane and lithium-tert.-butylamide give the bis(amino)-bis(pyrrol-1-yl)silane 4, however, with tert.-butylamine the mono(amino)-chlorobis(pyrrol-1-yl)silane 5 is formed. 3 and 5 are two more examples for the rare NH-functional chlorosilanes. Depending on the stoichiometry the methylamino(pyrrol-1-yl)silanes 6 and 7 are formed in the reaction of dichlorobis(pyrrolyl-1-yl)silane and methylamine. 7 is formed with displacement of the pyrrolyl-substituent by the more basic methylamino-group. 1 and 2 can be dilithiated and added to difluorosilanes leading to the cyclodisilazanes 8-10. 1.3.5-Tris(fluorodimethylsilyl)hexamethylcyclotrisilazane is an educt for pyrrol-1-yl- and (indol-1-yl)silylhexamethylcyclotrisilazanes 11-14. It reacts with one equivalent of lithiumpyrrolide or -indolide to 11 and 12 or with two or three equivalents of lithiumpyrrolide to 13 and 14. The 1.3-bis((N-(indol-1-yl)dimethylsilyl)aminodimethylsilyl)-2.4-bis(dimethyl)cyclodisilazane 15 is formed in the reaction of 1.5-bis(fluorodimethylsilyl)octamethylcyclotetrasilazane with lithiumindolide which catalyzes the ringcontraction. The crystal structure of 14 is reported.
