Abstract The successive stabilityconstants of La(III) with somearylhydrazones of benzylacetone (BAAH) and dibenzoylmethane (DBMAH) have been determined potentiometrically following the Bjerrum pH-metric titration. The stabilityconstants of the metal chelates are correlated to the Hammett substituent constant (σ x ) and to the molecular structure. The structures of the complexes have been assigned on

The formation of thioglycosides 7a-j and 10a-j via the reaction of sodium salts of thiopyridines 3a-e with glycosyl bromides 6a,b has been studied. Comparison with the products obtained from silylated thiopyridines 8a-e and peracetylated sugars 9a,b is made. C-13 NMR was utilized to elucidate the proposed structures of the products.
