Metal-free trans -hydroboration without a B-H bond: reactions of propargyl amines with Lewis acidic boranes

The first alkyne -hydroboration reaction without a B-H bond was described. This was achieved by reactions of propargyl amines with Lewis acidic boranes under mild conditions. The mechanism involved borane-mediated alkyne activation and intramolecular hydride transfer, thus realizing a unique hydrobo...

Zusammenfassung:The first alkyne -hydroboration reaction without a B-H bond was described. This was achieved by reactions of propargyl amines with Lewis acidic boranes under mild conditions. The mechanism involved borane-mediated alkyne activation and intramolecular hydride transfer, thus realizing a unique hydroboration in the absence of a B-H bond.
