On the use of seven-membered phosphorous heterocycles based on 2,2′-dihydroxy-1,1′-binaphthalene and 1,4∶3,6-dianhydro-d-mannitol in the31P NMR analysis of the enantiomeric composition of chiral alcohols
摘要:
Some aspects of phosphorylation of 2,2'-dihydroxy-1,1'-binaphthalene (BINOL) and 1,4:3,6-dianhydro-D-mannitol (isomannide) were investigated. The possibility of using the corresponding cyclic chloro-and amidophosphites for the analysis of enantiomeric compositions of chiral primary and secondary alcohols by P-31 NMR was examined.
Fluoride-ion-mediated Hydrolysis of Phosphoric Acid Esters, Amides, and Phosphorous Acid Esters Leading to Phosphorofluoridic, Phosphoramide Fluoridic, and Phosphonic Acid Monoester Salts
Fluoride-ion-promoted hydrolysis of phosphoric acidesters and amides to give phosphorofluoridic and phosphoramide fluoridic acid monoester salts takes place upon treatment with a THF solution of T...
