银(I)催化的炔酮与醇的反应是合成1-烯基异色胺的一种常用手段。这个反应很可能是通过苯并吡啶离子的形成进行的，然后苯并吡啶离子受到醇的亲核攻击，产生环状产物。
The silver(I)-catalyzed reaction of alkynones with alcohols represents a general tool for the synthesis of 1-allenyl isochromenes. The reaction most probably proceeds via the formation of benzopyrylium cation, which subsequently undergoes nucleophilic attack of an alcohol to give the annulation products.
