Bis(carbyne) complexes are discussed as key intermediates of numerous CC coupling reactions of carbyne‐complexes to alkyne complexes—an experimental detection of such intermediates has now been possible in the reaction of the cationic bis(carbene) complex 1 with bromine or ethyl isocyanide, which leads to the alkyne complexes 2 and 3 (see also Highlight on p. 1119). Thus, in principle, the prerequisites under which processes such as the catalytic hydrogenation of CO proceed, are now also better understood. Counter ion = BF 4 ⊖ .
