Several cyclic and acyclic enones and their ethylene ketals/acetals were reacted with dimethyl diazomalonate under bis(acetylacetonato)copper(II) catalysis. Cyclohex-2-en-I-one (1) yielded only C-H insertion products 2 and 3, whereas but-3-en-2-one gave a cyclopropane albeit in very low yield. The e

The copper complex, 3-ethoxy-2axobutyraldehyde bis(thiosemicarbazonato) copper( slowly oxidizes thiol groups. Under conditions of excess thiol, the reaction leads to the dissociation of CuKTS\_ On the basis of pH and concentration studies of the rate of reaction, mechanisms are proposed for the reac
