STEREOSELECTIVE ADDITION OF CARBOXYLIC-ACIDS TO ELECTRON-DEFICIENT ACETYLENES CATALYZED BY THE PDMO3S4 CUBANE-TYPE CLUSTER
zThe mixed-metal sulfide cubane-type cluster complex [PdMo3S4(tacn)(3)Cl][PF6](3) (1; tacn = 1,4,7-triazacyclononane) was found to be a highly efficient and selective catalyst for the addition of carboxylic acids to acetylenes with electron-withdrawing groups. The corresponding trans addition produc...

Summary: | zThe mixed-metal sulfide cubane-type cluster complex [PdMo3S4(tacn)(3)Cl][PF6](3) (1; tacn = 1,4,7-triazacyclononane) was found to be a highly efficient and selective catalyst for the addition of carboxylic acids to acetylenes with electron-withdrawing groups. The corresponding trans addition products were exclusively obtained in good yields under mild reaction conditions in the presence of a catalytic amount of triethylamine. |
