conditions the thermal elimination of Ph3PO from β-oxoalkylidenetriphenylphosphoranes, previously confined to cases with an α-electron withdrawing group, has been extended to provide a general, high yielding synthesis of aliphatic and terminal alkynes.
通过使用快速真空条件,从以前局限于具有电子吸电子基团的情况下,从β-氧代亚烷基三苯并三苯膦中消除Ph 3 PO的范围扩大了,从而提供了一种通常的高产率的脂肪族和末端炔烃合成方法。
