In the presence of catalytic amounts of Rh2(OAc)4 in toluene, dimethyl diazomalonate (1) decomposed with evolution of N2 to form a carbenoid of type 8 which reacted with carboxamides 2 and toluenesulfonamide (4) to give 2-(acylamino)- and 2-(sulfonylamino)malonates 3 and 5, respectively. In an analogous reaction, α-diazo ketone 6 and 4 yielded N-(2-oxo-1,2-diphenylethyl)toluenesulfonamide (7).
