Diazomalonic esters offer ready access to some classes of geminally disubstituted cyclopropanes, endo-substituted bicyclo[n.1.0] systems, and selectively cyclopropanated polyolefins as well as some classes of olefins bearing ether, sulfide, and halogen substituents. The current scope and limitations of synthesis involving these systems are illustrated. 1. Preparation of Diazomalonic Esters 2. Reaction with Saturated C-H Bonds 3. Reactions with Olefins 4.
