    Title: Cycloaddition of 1,1,2,2-Tetrafluoro-1,2-disilacyclobutene with Aldehydes and Ketones. II – Conjugated Aldehydes and Sterically Hindered Ketones
    Authors: Lu, Y. B.;Liu, C. S.
    教師: 劉兆玄
    Date: 1983
    Publisher: Elsevier

    Keywords: Cycloaddition
    Aldehydes
    Abstract: The reactions of 1,1,2,2-tetrafluoro-1,2-disilacyclobutene with benzophenone, pinacolone, acrolein and crotonaldehyde are studied at −30°C. The product formation is best rationalized in terms of an initial attack by the carbonyl oxygen on one of the two silicon atoms, which assists the cleavage of the Si-Si bond to form a diradical intermediate, followed by either ring closure or hydrogen abstraction. The reactions are so chosen to provide information about steric, inductive and resonance effects.
