"The interaction of diazomalonic esters with olefins in the presence of homogeneous Cu(II) catalyst species has been examined relating to olefin structure effects and catalyst structure effects using partial rate data as a method of determining the mechanistic aspects of the various reactions.
It has been possible to examine the mechanistic details of cyclopropanation, C-H insertion, and both "dimer" forming reactions.
Cyclopropanation proceeds via a transition state including olefin, copper (II), ligands, and carbene C-H insertion results from hydrogen abstraction prior to collapse of the transition state. "Dimer" is formed by the attack of diazo compound on the carbenoid carbon, with subsequent trans elimination of nitrogen and catalyst.
The first copper catalyzed decomposition of a Δ-1 pyrazoline has been observed"--Abstract, page iii.
