Structure and properties of metal complexes of a pyridine based oxazolidinone synthesized by atmospheric CO₂fixation

Abstract

Copper, platinum and palladium complexes of an oxazolidinone ligand show potential in catalysis or cytotoxicity, depending on the metal incorporated.

A self-assembled bisoxazoline/Pd composite microsphere as an excellent catalyst for Suzuki–Miyaura coupling reactions

“…30,31 However, it is difficult to distinguish the 1 H NMR spectral difference between the novel bisoxazoline ligands and their metal complexes owing to their poor solubility in DMSO-D 6 . The 1 H NMR spectral difference between the novel oxazoline ligands and their metal complexes is one of the important methods for characterization of complexes in the literature.…”

The crystal structure of a novel Pt(II) complex with 2¬-hydroxy-6-methylpyridine (Hmhp), trans-[PtCl2(dmso)(Hmhp)]·H2O

“…The four-fold coordination environment of platinum(II) consists of two trans positioned chlorides, a 2-hydroxy-6-methylpyridine ligand (Hmhp) and a dimethyl 0.0310 wR2 [b] [all data] 0.0809 (2-pic = 2-methylpyridine). [16][17][18] The platinum coordination environment in the latter complexes is highly reminiscent of that in the title compound: two trans positioned chlorides, a dmso ligand and an aromatic ligand bound via a nitrogen donor atom. The platinum-to-chloride bond lengths, 2.2884 9 17,19 The 2-hydroxy-6-methylpyridine ligand is bound to the metal ion via a nitrogen at 2.067(4) Å, a slightly longer distance than 2-picoline in trans-[PtCl 2 (dmso)(2-pic)] with the platinum-to-picoline bonds of 2.046(10) Å.…”

Substrate-Assisted Carbon Dioxide Activation as a Versatile Approach for Heterocyclic Synthesis

“…Their cyclization with CO2 leads to the formation of cyclic carbamates and these 5-membered heterocyclic products are usually described as oxazolidinones. These compounds are versatile chemical products that have found application in various fields of chemistry, for instance as chiral auxiliaries, 42 scaffolds for antimicrobial drugs 43 or antidepressants, 44 and in organic synthesis. 45 In contrast to the large number of reactions based on propargylic alcohols that emerged during the end of the last century, relatively few examples have been reported for propargylic amines, probably due to the fact that the latter have more restricted accessibility.…”
