| Outline of Final Research Achievements |
Through this research, we tried to clarify the features of the group 6-7 metals, especially unknown and useful reactivities for organic synthesis. We have found the following synthetic reactions by using the metal complexes. (1) Isolation of silyl-substituted gem-dichromiomethane (and gem-dizinciomethane) complexes and examination of the catalytic reactivity of the isolated complexes toward olefins and carbonyl compounds; (2) Intermolecular anti-Markovnivov addition of carbon nucleophiles by generation of rhenium-alkylidene complexes from terminal alkynes; (3) Molybdenum-catalyzed hydrosilylation of allenes and deoxygenation of epoxides; (4) Novel bismuth-catalyzed electrophilic C-C bond formation and etherification of phenolic hydroxy groups.
