Abstract

The coupling reaction of terminal alkynes and tert-butylisonitrile to yield substituted α,β-acetylenic aldimines is catalyzed by the organoactinide neutral complexes Cp*₂AnMe₂ (Cp* = C₅Me₅, An = Th, U) and the cationic complex [(Et₂N)₃U][BPh₄]. The reaction proceeds by a 1,1-insertion of the isonitrile into the metal-acetylide bond. Additional insertion products can be obtained by altering the catalyst and the reactant ratios. A plausible mechanism for the catalytic reaction is presented, in addition to the crystal structure of Cp*₂UMe₂.
