Off and on: A nickel-catalyzed benzannulation of alkynylboronates provides functionalized phenols with high levels of chemo- and regioselectively. While transmetalation of organoboron intermediate to organonickel does not occur during cycloaddition, it is "switched on" by addition of base, thus allowing a one-pot benzannulation and cross-coupling to be realized (see scheme; Pin=pinacolato, Ms=mesyl).
