The outcome of rhodium(II) pivalate catalyzed decomposition of diaozoacetates in the presence of cyclohexane is highly dependent on carbenoid structure. Carbenoids derived from phenyldiazoacetates or diazoketoesters undergo high yielding intermolecular C–H insertions while other carbenoid systems undergo rearrangements, dimerization or trimerization.
