Abstract
Palladium catalysis was used in Stille-type carbonylative cross-couplings employing Mo (CO) 6 as the carbon monoxide source. Robust and convenient transformations were carried out in closed vessels at 100° C, providing a set of diaryl ketones in good yields. Aryl triflates and bromides were used as coupling partners with aryl stannanes. Inclusion of the Mo (CO) 6 destabilizing agent DBU made this protocol operationally simple and suppressed side- ...
