Chromacyclobutenes 2, which have been postulated as intermediates on several occasions , are unrealistic structures with incomplete electron shells and high energy. According to model calculations vinylcarbene complexes 3/4 are much more stable isomers and can be formed almost without activation energy from alkyne‐carbene complexes 1 . The different modes of coordination of the structure continuum 1–6 can be interpreted and predicted as a function of the metal complex ML n .
