Direct scandium- and lanthanum-catalyzed etherifications of propargyl alcohols 1 and 6 in MeNO₂-H₂O provided propargyl ethers 3, 4 and 7 in high yields. In addition, reactions of 1 and 6 with thiols exclusively yielded the corresponding propargyl sulfides.
在MeNO₂-H₂O中，钪和镧直接催化炔丙醇1和6的醚化反应，以高产率得到炔丙基醚3、4和7。此外，1和6与硫醇的反应仅生成相应的炔丙基硫醚。
