The reaction of uranacyclopropene complex (C5Me5)2U[η2‐1,2‐C2(SiMe3)2] with B‐aryl bis(alkynyl)borane PhB(C≡CPh)2 led to the first six‐membered uranium metallaboracycle, while the reaction with B‐amino bis(alkynyl)borane (Me3Si)2NB(C≡CPh)2 afforded an unexpected uranaborabicyclo[2.2.0] complex via [2+2] cycloaddition. The reaction with CuCl revealed the non‐innocent property of the rearranged bis(alkynyl)boron species towards oxidant. The reactions with isocyanide DippNC: (Dipp=2,6‐iPr2‐C6H3) and isocyanate tBuNCO afforded the novel uranaborabicyclo[3.2.0] complexes. All new complexes have been structurally characterized. DFT calculations were performed to provide more insights into the electronic structures and the reaction mechanism.
