title: Terminal alkyne activation by frustrated and classical Lewis acid/phosphine pairs.
abstract: Frustrated and classical Lewis pairs arising from combinations of Lewis acids and phosphines react with terminal alkynes either via C-H activation forming an alkynylborate salt or by addition to alkyne giving a zwitterionic phosphonium borate.
