Outline of Final Research Achievements |
Creation of novel reactive intermediates is a driving force for development of organic synthesis. In this project, we focused on metal-alkylidene (or carbene) complexes having carbon-metal double bonds. Some important / interesting results obtained during the project are as follows: (1) Schrock-type chromium (or titanium) alkylidene intermediates which can promote metathesis and cyclopropanation reactions were generated from newly isolated and structure- determined gem-dichromium (or dititanium) complexes. (2) Novel chromium-carbyne and -carbide complexes having three and four carbon-chromium bonds were prepared, respectively, and their crystal structures were determined. (Unexpected discovery) (3) A new generation method of molybdenum-carbene intermediates was developed using molybdenum(0) and o-quinone.
