Reaction ofo‐(HSiR₂)(BMes₂)C₆H₄with a fluoride ion: Fluoride attack at silicon and hydride transfer from silicon to boron to form FSi⋅⋅⋅HB interaction

Abstract

Reactions of o‐(HSiR2)(BMes2)C6H4 (R = Me (3a), Ph (3b)) with a fluoride ion afford [o‐(FSiR2)(HBMes2)C6H4]− (R = Me (5a), Ph (5b)), which involve the FSi⋅⋅⋅HB interaction to render the silicon atom pentacoordinate. The FSi⋅⋅⋅HB interaction in 5a was confirmed by X‐ray crystallographic analysis and “atoms‐in‐molecules” (AIM) analysis. © 2011 Wiley Periodicals, Inc.

Mechanism of Dehydrogenative Condensation of (o-borylphenyl)hydrosilanes with Methanol

“…The resulting barrier is 22.1 kcal/mol, significantly lower than that of Ia. This mechanism agrees with the push–pull mechanism suggested by Kawachi. , …”

“…This mechanism agrees with the push−pull mechanism suggested by Kawachi. 7,20 In the reaction pathway Ic, the alcohol approaches from a different angle. The proton from the hydroxyl group comes near to one of the phenyl rings of a mesityl group connected to the boron center.…”

N-Silylamines in catalysis: synthesis and reactivity

“…The reaction of o-(silyl)(dimesitylboryl)benzene with KF produced a borohydride species through the nucleophilic attack of fluoride at the silicon and the hydride transfer from silicon to boron. 40,41 Scheme 8 Alkaline earth metal catalysed dehydrocoupling of amines with silane.…”

Intramolecular HAr Ligand Exchange between Silicon and Boron: Functionality Transfer of SiH to BH

“…ortho ‐(Hydrosilyl)(boryl)benzenes 1 a and 1 b also reacted with KF in the presence of a cryptand to form hydridoborates 3 , which involved the unprecedented intramolecular FSi⋅⋅⋅HB interaction (Scheme ) 6d. The nucleophilic attack of a fluoride ion on the silicon atom triggers the hydride transfer from the silicon center onto the boron atom.…”
