WebThis method is simple and fast and involves automated SPE of the metabolites followed by derivatization with pentafluorobenzyl bromide and quantification by GC-MS. Dibutyl phosphate (DBP) serves as the internal standard. The detection limits for the six metabolites ranged from 0.1 to 0.15 ng/mL. WebCopper catalysis allows the direct oxygen-arylation of dialkyl phosphonates with diaryliodonium salts. This reaction proceeds with a wide range of phosphonates and phosphoramidates under mild conditions and gives mixed alkyl aryl phosphonates in very good yields and very good selectivity.
