form synthetically ubiquitous pinacol boronate esters or used in situ in Suzuki-Miyauracrosscouplings to generate 2,3-disubstituted heteroarenes from simple alkyne precursors in onepot. In a number of cases alkyne trans-haloboration occurs alongside, or instead of, borylative cyclization and the factors controlling the reaction outcome are determined.
