Towards molecules with monovalent elements of group 14. 2 papers in a new journal Nature Synthesis.

If you learned chemistry in school, you probably know that carbon and silicon have 4 valence electrons, i.e., they typically make 4 chemical bonds. If you continued to learn chemistry at a more advanced level, you likely heard about stable molecules with these atoms having 3 bonds (radicals), or stable molecules with divalent carbon/silicon - carbenes/silylenes (having 2 bonds). I am sure, however, that no one heard so far about stable molecules with monovalent carbon or silicon atoms. Well, here are the first examples. Or perhaps not really?.. See the new video about the publications in a new journal from the Nature group called Nature Synthesis.
