Isomeric distribution for the cyclopropanation of isoprene and 1,3-pentadiene with ethyldiazoacetate and competition studies of the cyclopropanation and diazo insertion into heteroatom–hydrogen bonds are also reported. All these results agree with a major electronic and steric influence on both the regiochemical and stereochemical control in the catalytic cyclopropanation and diazo insertion reactions
