Phosphorus fluoride exchange: Multidimensional catalytic click chemistry from phosphorus connective hubs
نویسندگان
چکیده
Phosphorus fluoride exchange (PFEx) represents a cutting-edge advancement in catalytic click-reaction technology. Drawing inspiration from nature’s phosphate connectors, PFEx facilitates the reliable coupling of P(V)–F loaded hubs with aryl alcohols, alkyl and amines to produce stable, multidimensional P(V)–O P(V)–N linked products. The rate P–F is significantly enhanced by Lewis amine base catalysis, such as 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD). substrates containing multiple bonds are capable selective, serial reactions via judicious catalyst selection. In fewer than four synthetic steps, controlled projections can be deliberately incorporated along three tetrahedral axes departing P(V) central hub, thus taking full advantage potential for generating three-dimensional diversity. Furthermore, late-stage functionalization drugs drug fragments achieved polyvalent hexafluorocyclotriphosphazene (HFP), has been demonstrated prior research.

Redox chemistry in the phosphorus biogeochemical cycle.
The element phosphorus (P) controls growth in many ecosystems as the limiting nutrient, where it is broadly considered to reside as pentavalent P in phosphate minerals and organic esters. Exceptions to pentavalent P include phosphine--PH3--a trace atmospheric gas, and phosphite and hypophosphite, P anions that have been detected recently in lightning strikes, eutrophic lakes, geothermal springs...
