Oligomeric Hindered Amine Phosphites as Polymer Stabilizers-Phosphorous Chloride Method- Unexpected Result: Formation of Macrocyclic Byproducts !!!
Phosphorus Containing Macrocycles in Synthetic Organic and Supramolecular Chemistry • Tricoordinated phosphorus containing macrocycles • can function as ligands for transition metal catalyzed reactions • (Heck reaction, hydroformylation, homogenous catalytic hydration, • Suzuki coupling, Sonogashira coupling etc.) • Pentavalent phosphoryl macrocycles • can be used for metal complexation and for molecular recognition of • H donating substrates also of biologically interesting compounds • such as amino acids
