Synthesis carbene complexes

A bidirectional benzannulation strategy allows the extension of an existing biaryl skeleton. The BINOL-derived bis-carbene complex 69, accessible through a sequence of regioselective double ortfio-lithiation/Fischer carbene complex synthesis, undergoes bidirectional benzannulation to give the dinuclear biphenanthrene complex 70. The optical induction exerted by the binaphthyl core is, however, only moderate a mixture of C2- and Cj-symmetrical bis(phenanthrohydroquinone) bis-chromium complexes is formed, in which the C2-...

Nitrogen often appears attached directly to carbon in Fischer-type carbene complexes. Equations 10.823 and 10.924 provide two examples of N-substituted carbene complex synthesis. The first procedure involves attack by the amide on one of the carbonyls (analogous to equation 10.6) followed by alkylation.
