Under H2 pressure, CoII(dmgBF2)2L2 (L = H2O, THF) generates a low concentration of an H? donor. Transfer of the H? onto an olefin gives a radical that can either (1) transfer an H? back to the metal, generating an isomerized olefin, or (2) add intramolecularly to a double bond, generating a cyclized radical. Transfer of an H? back to the metal from the cyclized radical results in a cycloisomerization. Both outcomes are favored by the low concentration of the cobalt H? donor, whereas hydrogenation and cyclohydrogenation are more likely with other catalysts (when the concentration of the H? donor is high).
