Alkynesdifunctionalization is a powerful strategy in organic synthesis that provides a convenient synthetic entry for internal alkenes. The main challenge in this field was considered to be the geometry control of the newly formed double bond (thermodynamically controlled or kinetically controlled). Herein, we report a novel procedure (through the cyclic compounds broken) to completely control the

base-promoted, allene-mediated cyclization of the alkynemoiety onto the nearby aromatic ring, substantial amount of the ketone resulting from hydration of the alkyne with adventitious water was discovered. The formation of the ketone of the anti-Markovnikov alkyne hydration was developed into a preparative method. This method, alternative to the common acid-and metal-catalyzed approaches, may be of particular
