alkyl or aryl group is placed at position 1 of the oQDM in its reaction with tungsten carbenecomplexes; however, a pyranylidene carbenecomplex is formed when a chromium carbenecomplex is used. Alternatively, the presence of bulky alkoxy groups in the FCC component favours a Diels–Alder aromatisation sequence, which leads to 1‐naphthyl FCCs. Furthermore, the isolation and the characterisation of several
