Synthesis of Phosphorus-Containing Macrocycles and Cryptands

Conformational Analysis of P,N‐Containing Eight‐Membered Heterocycles and Their Pt/Ni Complexes in Solution

“…In this context, metal complexes based on P,N-containing heterocycles are of interest, in particular, the cyclic diphosphine ligand P R 2 N R′ 2 (P 2 N 2 stands for a 1,5-R′-3,7-R derivative of 1,5-diaza-3,7-diphosphacyclooctane) contains soft coordination sites that allow a variety of metal complexes to be obtained. [37][38][39][40][41][42][43] These heterocycles can be obtained with various functionalization on the P and N atoms, which can be used to optimize target catalysts activity.…”

Synthesis, Characterisation and Reactivity towards PdII and PtII of ortho-, meta- and para-Xylyl-Based Phosphorus-Containing Macrocycles

“…[1] This is partially due to the air-sensitivity of the reagents used in their preparations and problems in isolating the final products, especially in the case of homoleptic polyphosphamacrocycles, [2] which are usually obtained by template methods. [3] Phosphathiamacrocycles are more accessible as free ligands and several examples can be found in the literature.…”

New Bifunctional Benzoxazaphosphorinanone Systems

“…The design and synthesis of new functionalized macrocycles for special applications is a subject of continuing interest [1,2]. Phosphorus-containing macrocycles have become increasingly interesting in recent years because of their applications in catalysis, chromatographic separation of metal ions, molecular recognition and biological applications [3±5].…”
