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. This strategy opens opportunities for new developments in the field of carbonyl-olefin metathesis, which traditionally relied on stoichiometric amounts of transition-metal reagents or photochemical promotion.
