demonstrates the first synthesis of cyclic (alkyl)(amino)carbene (cAAC) adducts of Hg(II), [cAACMe·HgBr(μ-Br)]2 (1a) and [cAACcy·HgBr(μ-Br)]2 (1b). Adduct 1b catalyzes intermolecular hydroamination of aromatic alkynes and amines under mild conditions to afford aromatic imines. The quest to prepare an electrophilic Hg(II) complex resulted in the synthesis of cationic [(cAACcy)2Hg(H2O)]2+2[NO3]− (3) by reacting
