摘要

n-Octyl ethers are obtained by reacting n-octyl halides with preformed alkoxides, or better, prepared in situ from ROH and solid KOH. Reactions are performed without any solvent but in the presence of a catalytic amount of tetra-alkyl ammonium salt (Aliquat 336). Good yields (⩾ 92% for primary R) are obtained at moderate temperatures and with easy work-up; for t- C4H9O-, elimination is a side reaction, and the effects of temperature and of the nature of ...
