摘要
Formal hydroboration of internal alkynes proceeds regio- and stereoselectively by the use of a diboron reagent masked with 1,8-diaminonaphthalene (dan) in the presence of readily available [(Ph3P)(3)CuCl], leading to direct formation of diverse B-protected alkenylborons in high yield. The B(dan) moiety can also be efficiently installed into the C-C double bond of alkenes to afford the respective alkylborons.
