摘要

The necessity of electron-withdrawing substituents is in accordance with previously reported results. 2., 3., and However, these cannot be attributed to a pure mesomeric effect, 3., and if comparing the partial addition to substrates like halobenzenes with cyano or nitrobenzenes. Rather, a mixture of electronic as well as conjugative effects seems to be important, with a predominance of conjugative effects. ... In summary we have shown that methoxylation of electron poor aryl alkynes ...
