Relationships between the carbon-oxygen stretching frequencies of carboxylato complexes and the type of carboxylate coordination

The surface and materials science of tin oxide

This account examines double asymmetric induction from theoretical and practical viewpoints. In the context of four major organic reactions-the aldol, Diels-Alder, catalytic hydrogenation, and epoxidation-it is shown that a double asymmetric induction can be analyzed in terms of the single asymmetric reactions of each of the two chiral reactants. A rule which qualitatively relates the results of these single asymmetric reactions with the outcome of the double asymmetric reaction is proposed. A powerful new strategy based on this rule for the predictable creation of new chiral centers is discussed and the use of this strategy for the synthesis of sugars and macrolides is presented.

Synthesis and Characterization of Some Dibasic Tridentate Schiff Base Ligands

The Schiff base condensation of 2,6-diacetylpyridine with aniline, p-methoxyaniline and benzylamine gives high yields of 2,6-diacetylpyridine-bis (arylimines). Complexation of 2,6-diacetylpyridinebis (anil) with nickel (II) and zinc (II) to form five- and six-coordinate complexes of the types MCl2·L and [ML2] (C104)2 illustrates the versatility of these new terdentate NNN donor ligands.
