T. Kondo et al., RUTHENIUM COMPLEX-CATALYZED ADDITION OF N-ARYL SUBSTITUTED AMIDES TO ALKYNES - NOVEL SYNTHESIS OF ENAMIDES, Journal of the Chemical Society, Chemical Communications, (4), 1995, pp. 413-414
The addition of N-aryl substituted amides to non-activated terminal al
kynes is efficiently promoted by the Ru-3(CO)(12)-PCy(3) catalyst syst
em, affording the corresponding linear (E)-enamides in good yields wit
h high regio- and stereo-selectivity.
