In the presence of 2.0 equiv of readily available tertiary alcohols such as <i>tert</i>-amyl alcohol, the methallylation products were prepared at room temperature in excellent yields. The salient features of the described process include simple operation, high efficiency, and mild reaction conditions. 2016-02-19 06:53:33 reaction conditions methallylation products 2.0 equiv room temperature
