Palladium-catalyzedaminocarbonylations of alkenyl chlorides, bromides, and triflates were investigated using Mo(CO)6 as a solid carbonmonoxidesource. The reactions afforded moderate to good yields producing a wide variety of acrylamides after 20 min of microwave irradiation. In addition, the aminocarbonylationreaction was, for the first time, expanded to include alkenyl phosphates as starting materials

A cobalt-N-heterocycliccarbene (NHC) catalyst efficiently promotes an ortho C-Halkenylation reaction of pivalophenone N-H imine with an alkenylphosphate. The reaction tolerates various substituted pivalophenone N-H imines as well as cyclic and acyclic alkenylphosphates.
