various alkynes in the presence of trimethylsilyl cyanide (TMSCN) by palladium(II) catalysis under aerobicconditions is investigated. This reaction includes two cyanation pathways, syn- and anti-cyanopalladation to alkynes that are activated by Pd(II). High syn-selectivity was observed in the reaction using terminal alkynes that have bulky substituents at a propargyl position and aliphatic internal
