A systematic study has been conducted of the catalytic reaction of diazomethane with cyclic and polycyclic unsaturated hydrocarbons, conjugated dienes, as well as with a series of functionalized unsaturated conpounds.The feasibility of using transition metal, nontransition metal, and rare earth metal compounds of, for example, Co, Ni, Zr, Rh, and Dy, has been demonstrated for the first time.It has also been established that Pd(acac)2 has very high activity as a catalyst for the cyclopropanation of terminal and endocyclic double bonds by diazomethane, and that its activity is reduced upon the introduction of n-donor ligands or in the presence of strong polar solvents.
Infrared Photochemistry of Bicyclopropyl

The decomposition of bicyclopropyl (C6H10) induced by multiphoton absorption from an infrared laser has been investigated.The reaction produces a complex product mixture consisting mainly of C6H10 isomers.A mechanism is proposed that can rationalize all of the existing infrared photochemical and thermal data on the basis of a single primary step, C-C bond cleavage to a 1,3-biradical.The product mixture results from competitive decay channels of the biradical and successive reactions of the ''hot'' products.This system provides a striking example of the influence of ''hot molecule effects'' on the product distributions in infrared multiphoton dissociation.
