  4. Abstract:
  5. (A) Chakraborty and co-workers have developed a green method for the bulk ring-opening polymerization of lactides in the presence of Cu(OAc)2 as a good catalyst to synthesize polymers with different end-terminal groups.3 These polymerizations are highly controlled leading to the formation of polymers with the expected number of average molecular weights and narrow molecular weight distribution. (B) Garden and co-workers have found that the oxidative addition of anilines with 1,4-naphthoquinone to give N-aryl-2-amino-1,4-naphthoquinones can be performed in the presence of catalytic amounts of copper(II) acetate.4 All the reactions are generally more efficient in that they are cleaner, higher yielding, and faster. (C) Wu and co-workers have developed a novel copper-catalyzed protocol for the synthesis of carbinol derivatives.5 In the presence of copper(II) acetate and dppf, carbinol derivatives were prepared by the addition of arylboronic acids to aromatic aldehydes in good to excellent yields. (D) The reactivity of copper(II) acetate as catalyst in standard C-O and C-N coupling reactions has been developed systematically.6 (E) Chemler and colleagues have found that Cu(OAc)2 is an excellent promoter for the intramolecular diamination of olefins using sulfamide substrates7 and oxidative cyclization of N-sulfonylated aromatic systems.8
