An analytical method for the determination of 14 organophosphorus flame retardants (OPFRs), including halogenated OPFRs, non-halogenated OPFRs and triphenyl phosphine oxide (TPPO) in biological samples was developed using gas chromatography-mass spectrometry (GC/MS). Biological samples were extracted using microwave-assisted extraction (MAE)

The methyl transfer from trimethyl phosphate to alkyl thiols was investigated in the presence of zinc ions and in the absence of strong base. The chelating thiol N-(2-mercaptoethyl)picolylamine (MEPAH) was methylated by trimethyl phosphate, in MeOH, in the presence of

Thymine residues in an oligodeoxyribonucleotide are subject to methylation at N3 by the internucleotide methyl phosphotriester linkages. This alkylation occurs most rapidly in the presence of a strong base such as DBU, but also takes place, at a much slower

Phosphate esters are important compounds in living systems. Their biological reactions with alcohol and thiol nucleophiles are catalyzed by a large superfamily of phosphatase enzymes. However, very little is known about the intrinsic reactivity of these nucleophiles with phosphorus centers.
