tert-Butoxytriphenylsilane

Abstract

The title compound, C22H24OSi or Ph3SiOtBu, shows a distorted tetra­hedral coordination sphere around the Si atom. The C—O—Si angle is 135.97 (12)° and the O—Si distance is 1.6244 (13) Å. The mol­ecules are held together by weak inter­actions only. An H⋯H distance of 2.2924 (7) Å is found between aryl H atoms and is the shortest inter­molecular distance in the structure. With regard to the broad applicability of R 3SiO structural motifs in all fields of chemistry, the mol­ecule demonstrates a common model system for silicon centers surrounded by sterically demanding substituents.

Molecular Structures of Enantiomerically-Pure (S)-2-(Triphenylsilyl)- and (S)-2-(Methyldiphenylsilyl)pyrrolidinium Salts

“…The hydrogen bond N-H(1N)···O (1) . The C-Si bond lengths of the triphenylsilyl moiety are comparable to those found in the hydrochloride species (S)-1·HCl [1] and in other triphenyl-substituted silanes [9,10]. The C(19)-Si bond between silicon and the heterocyclic carbon atom amounts to 1.9111(15) Å and is in the characteristic range for 2-(triphenylsilyl)pyrrolidines [1] (Figure 2).…”

“…The pyrrolidinyl nitrogen atom of (S)-1·HClO4 has been protonated by perchloric acid and is involved in hydrogen bonds to two perchlorate anions via H(1N) and H(2N). The hydrogen bond N-H(1N)···O (1) [1] and in other triphenyl-substituted silanes [9,10]. The C(19)-Si bond between silicon and the heterocyclic carbon atom amounts to 1.9111(15) Å and is in the characteristic range for 2-(triphenylsilyl)pyrrolidines [1] (Figure 2).…”

Controlled Synthesis and Molecular Structures of Methoxy‐, Amino‐, and Chloro‐Functionalized Disiloxane Building Blocks

“…The introduction of a triphenylsilyl group enables the study of functional group reactivity on only one silicon atom. Another advantage of Ph 3 E units (E = group 14 element) is that the crystallization tendency of molecules, which are otherwise difficult to crystallize, can be increased significantly . This allows studying the effects of functional groups directly attached to a silicon atom on structural parameters of the siloxane bond in the molecular crystalline material.…”
