  Four different complexes of the cobalt(II) acetate–pyridine–water system were obtained as dominant species by crystallization from a series of dichloromethane and toluene solutions. The complexes were characterized by terms of X-ray crystal structure determination. Factors in solution properties leading to crystallization of certain complexes are discussed. Furthermore, trends in terms of structure

  Novel cobalt thiobis (alkylphenolates) and coordination compounds thereof with alcohols, alkyl amines, or aryl amines are effective anti-oxidant additives for various organic media such as oils of lubricating viscosity and plastics. Synergistic and improved antioxidant combinations are formed from the admixture of said additives and known antioxidants such as N-phenyl-1-naphthylamine. Additionally, these cobalt thiobis(alkylphenolates), coordination compounds thereof and said combinations are also highly useful as energy quenchers and antisludging agents in organic substrates.

  Selective blocking of some amino groups in a polyamino organic compound having at least one pair of available neighboring hydroxyl and amino groups is effected by first preparing in situ transition metal salt complexes of available neighboring amino and hydroxyl group pairs in said polyamino organic compound, followed by introduction of blocking groups on the non-complexed amino groups and, finally, removing the transition metal cations from the selectively N-blocked polyamino organic compound complex to obtain a polyamino organic compound having selectively blocked amino groups. This process is particularly valuable when carrying out aminocyclitol-aminoglycoside transformations utilizing transition metal salt complexes of cupric acetate, nickel (II) acetate, cobalt (II) acetate or mixtures thereof.
