The vinylogous‐stabilized carbene complexes 2 (M Cr, W) are formed by successive reaction of the naphthoquinone bisketal 1 with t BuLi, M(CO) 6 , and a trace of acid. In the case of the simpler 1,4‐benzoquinone derivative, it is possible to prepare the carbene‐chromium complex 3 , which, as exprected, can undergo annelation with alkynes to form the B/C rings of anthracyclinones.
