Two classical antiaromatic molecules cyclobutadiene (CBD) and pentalene, were stabilized by introduction of one metal fragment through a [2+2] cycloaddition reaction of osmapentalyne with alkynes. As shown by J. Zhu, H. Xia et al. in their Communication on page 6181 ff., the metalla‐aromatic molecules absorb broadly from the UV to the near‐IR region and show photoacoustic and photothermal effects. Theoretical calculations reveal that the antiaromaticity of both CBD and pentalene is decreased.
