Abstract
10-Methoxy-9-oxa-10-bora[3.3.2]decane (1), easily prepared from the ox idation of B-MeO-9-BBN with trimethylamine N-oxide (TMANO), is readily converted to alkynylborinate complexes (2) with its reaction with rep resentative lithium acetylides. These complexes serve as efficient alk ynylating agents in the Suzuki-Miyaura coupling and their demethoxylat ion furnishes stable alkynylboranes (3) which also provide a convenien t new entry to cls-vinylboranes (5).
