Recently we have published synthesis methods for propargyl silane 1,3-difunctionalization with concomitant silyl shift. The concept involves propargylsilane activation with an electrophile, followed by a 1,2-silyl shift. This creates an electrophilic carbon center that can react with a nucleophile. This work presents a formal carbon electrophile to activate the propargylsilane. In this case aryl cuprate, generated from diaryliodane, activates the propargylsilane, which undergoes a 1,2-silyl shift. This generates a carbenium ion or its equivalent, which is trapped by the alcohol. Aromatic groups with electron donating and electron withdrawing substituents and some heteroaromatic groups can be used.
