This is a Heck Coupling, not a condensation. In a heck coupling, you have two subtrates. One, a sp2 hybridized halide or triflate, and a electron deficient terminal alkene. The two are coupled, and the product posseses a trans geometry.
The Pd(OAc)2 is the pre-catalyst, the PPh3 is the ligand, and the Sodium Acetate acts as a base and buffer. The Pd(OAc)2 disassocites the -OAc, and forms a Pd(PPh3)n species in situ. These low valent 14 (n=2)& 16 (n=3) electron species are very reactive, and oxidativly add a Bromobenzene to form Pd(PPh3)2BrPh, where Pd has inserted into the Ph-Br bond. It then loses a -Br, and coordinates in a eta-2 fashion to the pi system of the terminal alkene to give Pd(PPh3)2(CH2CHCONH2)Ph. The acetate then acts as a base when the terminal end of the alkene and the arene are coupled. The product is then reductivly eliminated, and the catalytic cycle continues. If you'll notice, the catalyst loading in this reaction is very low (101mg).
This reaction would apply to any substituted Bromo-, Iodo-, or Triflate substituted benzene.
