In addition, metallacyclopropane resonance structures will be used here throughout for convenience and uniformity, despite the fact that they are rarely used in the original publications to describe the putative reaction mechanisms of the late transition metals. Cyclopropyl activation in the addition reactions of alkylidenecyclopropanes are observed in the presence of various late transition metals, in particular nickel or palladium (Equations 18–21, 24–27). For example, palladium catalyzed addition of C─H and N─H acids to methylenecyclopro­ panes can proceed through cleavage of the distal cyclopropane C─C bond to give the corresponding 20 RING CLEAVAGE REACTIONS Cyclopropyl activation of distal cyclopropane C–C bond R E + (a) R + E+ E (b) + R Cyclopropylcarbinyl activation of proximal cyclopropane C–C bond Scheme 2.
