1,1-diborylation pre-print online

Appearing today in a pre-print on ChemRxiv, Yang and Zhong-Qiang describe a copper-catalyzed tandem process for preparing differentially protected E-configured 1,1-diboryl alkenes from terminal alkynes. Mechanistically the reaction proceeds through the intermediacy of an alkynyl–Bdan intermediate which undergoes in situ hydroboration. Special congrats to undergrad co-author, Zhong-Qian, who is headed to UChicago to start his Ph.D.
