| Outline of Final Research Achievements |
Various sequential formation of distant bonds was achieved by the use of functionalization reagents such as diborons and hydroboranes in the palladium-catalyzed chain-walking cyclization of 1,n-dienes. Sequential formation of "three" distant bonds, which is unprecedented and difficult to achieve otherwise, was also realized in the reactions of 1,n-dienes (n>6) with diborons. Formal sigma-bond metathesis between Pd-C and B-B bonds,a rarely considered process,is suggested to be involved in the final step of the catalytic cycles of the reaction using diborons and to proceed easily.
