双（碳炔）络合物被讨论为碳炔络合物到炔络合物的许多C-C偶联反应的关键中间体-在阳离子双（碳烯）络合物1与溴或异氰化乙酯的反应中，这种中间体的实验检测现在已经是可能的，该反应导致炔络合物2和3（也参见第1119页的Highlight）。 因此，原则上，现在也更好地理解了诸如CO的催化氢化等过程进行的先决条件。 反离子= BF 4-。[图片]
Bis(carbyne) complexes are discussed as key intermediates of numerous C - C 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 = BF4-.[GRAPHICS]
