摘要

The role of heteroatom-stabilized group 6 metal-carbene complexes as stable carbene sources has been extensively investigated. 1 In fact, the cyclopropanation of olefins was one of the earliest reactions reported for Fischer-type carbene complexes. 2 On the other hand, thermal decomposition (T> 130 C) of carbene complexes leads to carbene dimers. The E/Z ratio of the olefinic products is metal dependent, which excludes the participation of free ...
