Toward the Understanding of Modulation in Molecular Materials: Barluenga’s Reagent and its Analogues.
摘要:
Investigations into the phase transition of Barluengas reagent revealed a transient incommensurately modulated phase; the structures are presented herein. To understand the origin of the modulated phase and the chemistry that can affect it, analogues of Barluengas reagent were synthesized and studied. In this context, the halogen and anion can easily be exchanged. Studying different analogues led to the development of the Ratchet Model to describe the behavior in the solid state leading to a better understanding of modulation in this class of molecular crystal structure.

The stereospecific intramolecular hydroamination of alkynyl trichloroacetimidates catalyzed by bis(pyridyl)silver(I) complexes to form 1,3‐oxazolines and oxazines has been investigated in greater detail. The rate of the reaction is profoundly influenced by the electronic character of the pyridyl ligand; leading to optimized conditions whereby reactions can be completed at ambient temperature with catalyst

Two new coordination polymers, Ag2[Pt(ox)2]·2H2O (ox = oxalate) and [Ag(H2O)]2[Ag2(CF3SO3)4][Pt(acac)2]2, which are formed by short platinum to silver dative bonds, were synthesized and structurally characterized.
