Ketene alkyltrialkylsilyl acetals: synthesis, pyrolysis and NMR studies
221
TL;DR: In this article, it was shown that the freedom of rotation about a carbon carbon double bond is determined by the attached substituents, and the mechanism of this reaction has been established as intramolecular employing 18O.
