Synthesis of the isolable biradicals *(CH3B)11C-C triple bond C-C(BCH3)11* and trans-*(CH3B)11C-CH=CH-C(BCH3)11*.
A synthesis of ethene and ethyne derivatives carrying the anionic -C(BCH3)11- substituent on one or both carbon atoms is described. Two-electron oxidation of the dianions yielded the stable and isolable electroneutral title biradicals.
