Abstract
AbstractA (3+2) cycloaddition reaction of linear N,N‐disilyl enamines and organic azides is investigated. The N,N‐disilyl enamines, derived from the selective double hydrosilylation of conjugated nitriles, are employed in‐situ for this investigation. The resulting triazoline intermediate from the (3+2) cycloaddition reaction promptly undergoes retro‐(3+2) cycloaddition to yield versatile non‐stabilized diazoalkane, along with formamidine. The presence of a transient and unstable alkyl diazomethane is confirmed by utilizing carboxylates as trapping reagents. Furthermore, we demonstrate the versatility of these alkyl diazomethanes by utilizing them in reactions with various reagents, including hydroborane, diboron, silaborane, alkenes, and alkynes.
