The Use of Potassium Phosphonate (KHP) for the Control of Major Apple Pests

Plant Disease, 2022
Phosphonate-based products have demonstrated diverse abilities to protect crops against pests, with various modes of action proposed. In this article, we specifically investigated potassium phosphonate (KHP) on apple crops. Its performance to control three major apple bioagressors (Venturia inaequalis, Erwinia amylovora, and Dysaphis plantaginea) was ...

Octa- and hexametallic iron(iii)–potassium phosphonate cages

Dalton Transactions, 2011
Two new iron(III)-potassium phosphonate cage complexes with {K(2)Fe(6)} and {K(2)Fe(4)} cores are reported. Magnetic studies reveal antiferromagnetic interactions between the Fe(III) centres occur in these cages.

Facile preparation of potassium 32P-phosphonate

Journal of Radioanalytical and Nuclear Chemistry, 2004
Simple and easy to operate experimental assemblies were for the first time designed for the successful preparation of potassium 32P-phosphonate from 32P-orthophosphate. Phosphate was first converted to phosphoryl chloride by reacting with phosphorus pentachloride. Then the phosphoryl chloride formed was reduced to phosphorus trichloride by heating with

Palladium(II)-Catalyzed Ortho-Arylation of Benzylic Phosphonic Monoesters Using Potassium Aryltrifluoroborates

The Journal of Organic Chemistry, 2013
The new monophosphonic acid directing group was successfully utilized in the Pd (II)-catalyzed ortho-arylation of benzylic phosphonic monoesters using potassium aryltrifluoroborates. A wide range of benzylic phosphonic monoesters underwent clean ortho-arylation in high yields, and excellent functional group tolerance was also observed.
