Outline of Final Research Achievements |
Catalytic reactions that involve the cleavage of a carbon-heteroatom bond were examined, in particular, focusing on those through the formation of onium salts. This led to the development of nickel-catalyzed synthesis of phospholes from bisphosphines via the double cleavage of carbon-phosphorus bonds. A similar transformation using the corresponding sulfur analogs was found to be catalyzed by a thiolate base. Intermolecular annulation between triarylphosphines and arynes to form phosphole derivatives via the cleavage of a carbon-phosphorus bond was also developed.
