“…Using silanediol-based ligands, Krempner and co-workers synthesized disilyloxide-scaffolded aggregates, each with a welldefined trinuclear Zn 3 O 4 core. 259 To ascertain the reactivity of some of the aggregates, B(C 6 F 5 ) 3 was used and found to not only abstract methyl groups from the terminal ZnMe groups, but replace them with C 6 F 5 groups to form 187 and 188 in 67% and 61% yields, respectively (Scheme 94). In another methyl abstraction reaction with B(C 6 F 5 ) 3 , Vigalok and co-workers studied the reactivity of some calixarene-ligated dinuclear alkylzinc complexes.…”

Die Synthese, Struktur und exemplarische Reaktivität von Siloxiden mit planarchiralem N,N‐Dimethylaminomethylferrocen‐Rückgrat wird vorgestellt. Mehrere Zinkkomplexe ausgehend aus dem racemischen als auch dem enantiomerenreinen Silanol wurden in Gegenwart von Wasser synthetisiert, kristallographisch charakterisiert und auf ihr Verhalten in Lösung untersucht. Die in diesem System vorhandene chirale Sonde stellt sich als wertvolles Werkzeug zur Identifizierung der vorliegenden Struktur in Lösung heraus. Weiterhin zeigen die Zinksiloxide eine vergleichbare Reaktivität wie die entsprechenden Silanole. Daher bieten sich diese als “maskierte” Silanole an, vor allem dann, wenn die Silanole präparativ unzugänglich sind.

We present the synthesis, structure, and exemplary reactivity of siloxides with a planar-chiral N,N-dimethylaminomethylferrocene backbone. Several zinc complexes based on the racemic as well as the enantiomerically pure silanol were synthesized in the presence of water and crystallographically characterized, and their behavior in solution was examined. The chiral probe present in this system is a valuable tool for identifying the structure in solution. Furthermore, the zinc siloxides exhibit a comparable reactivity to the corresponding silanols. Therefore, they can be regarded as "masked" silanols, especially when the silanols are preparatively inaccessible.
