Electrooxidative cleavage of carbon-carbon linkages. 1. Preparation of acyclic oxoalkanoates from 2-hydroxy- and 2-acetoxy-1-cycloalkanones and cycloalkanone enol acetates
Various cyclic α,β-epoxy ketones rearranged to α-formyl ketones and/or vic-diones in the presence of catalytic amounts of zeolites and montmorillonite K10. This provides an excellent alternative to conventional homogeneous systems with respect to yields and workup. Differences in product distribution and type of products in the rearrangement of pulegone oxide could be reasonably explained by invoking
A C60 derivative bearing an organofluorine tail through the dimethylsilyl moiety (1) was proved to be an efficient photosensitizer in C6F6. Photooxygenation of olefins or dienes was accomplished by catalysis of 1 (0.5–1.5 mol%) at room temperature under an oxygen atmosphere.
