A simple and efficient strategy to construct aromatictertiary amines via a double Petasis–borono Mannich reaction of aromatic amines, formaldehyde, and organoboronic acids has been developed. The transformation provides a useful method for the synthesis of amine derivatives.

[(cod)RhCl]2 in the presence of CO gives the cyclopentadienone complex [(Cpd’)Rh(CO)Cl]n (Cpd’ = TsN(CH2)2C4(Tol)2CO). Its dissolution in DMSO or pyridine leads to decarbonylation and formation of the adducts (Cpd’)Rh(DMSO)2Cl and (Cpd’)Rh(Py)2Cl. The reaction of [(Cpd’)Rh(CO)Cl]n with AgPF6 and p-xylene produces the sandwich arene complex [(Cpd’)Rh(p-xylene)]PF6, in which the arene can be substituted
