Alkynes undergo smooth coupling with aldehydes in the presence of Amberlyst-15® at room temperature to produce the corresponding α,β-unsaturated ketones in high yields with E-geometry. The use of an inexpensive, readily available, and recyclable cation exchange resin makes this method quite simple and convenient.
炔烃经历与在的Amberlyst-15的存在的醛平滑联接®在室温下,以产生高的产率与相应的α,β不饱和酮É -geometry。使用便宜,易于获得且可回收的阳离子交换树脂使该方法非常简单和方便。
