Acetyldimethylphenylsilan (2) reagiert bei Raumtemperatur mit TBAF · 3H\(_2\)O in THF bzw. mit KF in DMSO/H\(_2\)O zu [(CH\(_3\))\(_2\)SiO]\(_x\) und 1-Phenylethanol (3), welches mit praktisch quantitativer Ausbeute isoliert werden kann. Dieses Reaktionsverhalten von 2 gegenüber F\(^-\) weicht drastisch ab von dem in der Literatur beschriebenen Verhalten einiger Aroyl- und Heteroaroyltrimethylsilane. Ein Reaktionsmcchanismus, der u.a. eine 1,2-Phenylverschiebung und eine BrookUmlagerung beinhaltet, wird zur Diskussion gestellt.
