Outline of Final Research Achievements

Catalytic cleavage of C-C bonds is familiar for highly strained compounds. However, the C-C bond cleavage of non-strained linear alkanes is not common. This work focused on the finding of a useful catalytic system for C-C bond cleavage available for non-strained linear alkanes. After the survey of the catalytic systems, iridium catalyst was found to show excellent catalytic activity for C-C bond cleavage of linear alkanes, such as nonadecane under hydrogen atmosphere at heated conditions (250-270°C). The reaction completed with the complete conversion to methane. The time course experiment revealed that C-C cleavage took place from the edge. The catalytic C-C cleavage reaction was successfully applied to cyclododecane, which proceeded via hydrogenative ring-opening.　The catalyst can be used at least four times without loss in the activity.
