Allene (1) was prepared according to a previously described method [25, 26].
Recycling studies were carried out using the procedure for the hydroamination of allene (1) (0.27 mmol) with aniline (0.81 mmol), Pd catalyst (Si[O.sub.2]@ imineNB-Pd-II, 90 mg, 5mol%), trifluoroacetic acid (20mol%), and THF (0.5 mL).
The heavy allenes show at least two bands in the [pi][right arrow][[pi].sup.*] band regions of disilenes and digermenes.
