  • Radicals of heavy main-group elements represent important intermediates in chemical synthesis, yet few have been isolated. Here the authors stabilize neutral stibinyl and bismuthinyl radicals using gallium-based ligands, and reduce the former to afford a Ga=Sb double bond-containing complex.

  • The synthesis, structure and reactivity of room-temperature-stable [Cp(C6F5)5]+[Sb3F16]− is presented. Coordination of the cyclopentadienyl cation by [Sb3F16]− or C6F6 stabilizes the antiaromatic singlet state in the solid state. Calculated hydride and fluoride ion affinities of the [Cp(C6F5)5]+ cation are higher than those of the tritylium cation [C(C6F5)3]+.

  • Compounds of main-group elements rarely undergo direct carbonylation reactions. Now, an electron-rich silylene intermediate has been shown to readily react with CO to form a silylene carbonyl complex that is stable at room temperature. This complex engages in CO substitution as well as oxidative addition reactions.
