The hydroamination of alkynes using o-aminophenol proceeds in very high to good yields in the presence of Pd(NO3)2 catalyst. Remarkable rate enhancement with o-aminophenol is presumably due to the chelation effect of the ortho OH group to palladium.

A Synthesis of (<i>E</i>)-(1-Organo-1-alkenyl)boronates by the Palladium-Catalyzed Cross-Coupling Reaction of (<i>E</i>)-1,2-Bis(boryl)-1-alkenes with Organic Halides: A Formal Carboboration of Alkynes<i>via</i>the Diboration-Coupling Sequence
(E)-1,2-Bis(boryl)-1-hexene, prepared by the platinum-catalyzed diboration of 1-hexyne with bis(pinacolato)diboron, regioselectively cross-coupled with aryl, 1-alkenyl, benzyl, and allyl halides in the presence of a palladium catalyst and a base to provide the corresponding pinacol esters of (E)-(1-butyl-1-alkenyl)boronic acid in good yields.
