Other Catalytic Reactions via Allenylidene Complexes as Key Intermediates

Other Catalytic Reactions via Allenylidene Complexes as Key Intermediates 

After our discovery of the chalcogenolate-bridged diruthenium complex-catalyzed propargylic substitution reactions of propargylic alcohols with a variety of nucleophiles via allenylidene intermediates, as described in the previous sections, some 

Results of catalytic reactions in which allenylidene complexes work as catalytic precursors [51] are not included in this chapter. 

This chapter is mainly a summary of our recent findrngs on the thiolate-bridged drruthenium complex-catalyzed novel organic transformation of propargylic alcohols.
