The present invention provides, inter alia, organocatalytic carbonyl-olefin metathesis process. This process involves contacting a carbonyl-containing moiety with an olefin-containing moiety in the presence of a catalyst and under conditions sufficient to form a metathesis product with the proviso that the process takes place in the absence of photochemical promotion, stoichiometric amounts of transition metals, and Brnsted and Lewis acid catalysts. The present invention also provides an organocatalytic olefin-olefin metathesis process. This process involves contacting a first olefin-containing moiety with a second olefin-containing moiety in the presence of a catalyst and under conditions sufficient to form a metathesis product with the proviso that the process takes place in the absence of stoichiometric amounts of transition metals. Products made by the processes disclosed herein are also provided.

The development of a catalytic carbonyl-olefin metathesis strategy is reported, in the context of the ring-opening metathesis of cyclopropenes with aldehydes using a,simple hydrazine catalyst The key to this reaction is 4 conceptual blueprint for metathesis chemistry that forgoes the traditional reliance on [2 + 2] cycloaddition modes in favor of a [3 + 2] paradigm.
