摘要

Abstract Addition of benzeneselenol to terminal alkynes HCÍÄCR, catalyzed by Pd (0) complexes, leads to formation of mixtures of mono-and bis (phenylseleno) alkenes, depending on the nature of the R substituent. Electron-donor groups (R= Bu, CH 2 OH, CH 2 NMe 2) give rise to addition according to the Markownikoff rule, whereas from alkynes with electron-acceptor groups (R= Ph, COOMe) mixtures of products are formed as a result of ...
