Sterically hindered P,N-type amidophosphines {(o-PPh2)C6H4}C(O) NH(R)}: synthesis, transition metal chemistry, and catalytic activity in stereoselective Heck coupling of aryl chlorides

This paper reports the synthesis, coordination chemistry, and catalytic applications of two amide-based monophosphine ligands, {(o-PPh2)C6H4}C(O)N(H)(C12H18)} (L1) and {(o-PPh2)C6H4}C(O)NH(C33H28)} (L2). Ligand L1, upon reaction with [Pd(COD)Cl2] and [Pd(OAc)2], yielded dimeric...
