In this contribution, we illustrate uranium complexes bearing a pendant borate (i.e. 1 and 2) or borane 3 4) moiety via reaction of the highly strained uranacycle I with various 3-coordinate boranes. Complexes 4 represent first examples Lewis acid. Moreover, complex was capable activation CO, delivering new CO mode, an abnormal 1,2-insertion pathway into U-N bond. The importance confirmed by controlled experiments.
