Title	Palladium(II) p-Tolylamide and Reaction with CO₂ to Generate a Carbamato Derivative
Author	Jung Min Seul, Soonheum Park*
Keywords	Palladium arylamide, Palladium carbamate, Insertion of CO₂, Methyl N-aryl carbamate
Abstract	Pd(II) p-tolylamide Pd(2,6-(Ph₂PCH₂)₂C₆H₃)(NH(C₆H₄Me-p)) (1) was metathetically prepared by the reaction of Pd(2,6-(Ph₂PCH₂)₂C₆H₃)Cl with NaNH(C₆H₄Me-p). Treatment of 1 with carbon dioxide affords the palladium(II) carbamate Pd(2,6-(Ph₂PCH₂)₂C₆H₃)(OC(O)NH(C₆H₄Me-p)) (2), quantitatively. Complex 2 reacts with HX (X = Cl, OTf) to give Pd(2,6-(Ph₂PCH₂)₂C₆H₃)X, NH₂(p-Tol) and CO₂. Reaction of the palladium(II) carbamate with MeI produced Pd(2,6-(Ph₂PCH₂)₂C₆H₃)I along with generation of methyl N-tolylcarbamate MeOC(O)NH(C₆H₄Me-p), exclusively.
