The direct metalation of phthalazinium halides with [Rh(tBuO)(COD)]2 or [Ir(tBuO)(COD)]2 led to the isolation of stable [MCl(phthalazin-2-ylidene)X(COD)] (M = Rh, Ir) as a new family of cyclic amino aryl carbene transition metalcomplexes. The X-ray diffraction analysis of several representatives systematically revealed a relatively short C(aryl)−C(carbene) bond distance of 1.44−1.46 Å, shorter than

1-Hydroxy-2-aryl-1,2-dihydrophthalazines are dimerized to give 1,1′-bi-(2-aryl-1,2-dihydrophthalazinylidenes); an X-ray crystal structure shows a relief of strain in these compounds by a trans-foldedalkenelinkage and a buckling of the phthalazinyl ring.
