Epoxides and phosphites are often used as additives to stabilize the properties of polymers, including bisphenol A polycarbonate (BPA-PC). We describe density functional (DF) calculations of the reactions of cyclohexene oxide (CHO, cyclohexane epoxide) and phosphites with chain segments of BPAPC, with the aim of identifying possible reaction paths and energy barriers. The reactions of CHO with ...

This study tested the efficacy of five different phosphites (calcium, copper, magnesium, potassium and zinc/manganese phosphites) a fungicide Fosetyl-Aluminum to inhibit bacterial speck disease severity caused by Pseudomonas syringae pv. tomato (Pst) on leaves. The were applied at recommended doses Pst inoculated plants in pots foliar spraying one-week intervals for total 4 weeks. kept controll...

The hydrogenation of 2-methylquinoline with Ir catalysts based on chiral phosphine-phosphites has been investigated. It has been observed that the reaction is very sensitive to the nature of the ligand. Optimization of the catalyst, allowed by the highly modular structure of these phosphine-phosphites, has improved the enantioselectivity of the reaction up to 73% ee. The influence of additives ...

Nucleophilic addition of phosphinic acid, phosphites, sodium dialkyl phosphites, phosphoramidites, phosphinites, and phosphonites to highly polarized or cationic fluorophores, followed by oxidation, results in new "PONy" dyes with auxochromic phosphinate, phosphonate, or phosphonamidate groups. The reaction was applied to a wide variety of coumarins, (thio)pyronins, and N-alkylacridinium and 5,...

Chiral phosphine-phosphites provide versatile catalysts for the highly enantioselective hydrogenation of alpha-acyloxy alpha, beta-unsaturated phosphonates.

An organocatalytic enantioselective addition reaction of cyclic ketoimines with phosphites has been developed for the first time. The process, catalyzed by Soós' quinine thiourea, affords synthetically and medicinally interesting enantioenriched trifluoromethyl dihydroquinazolinones in high yields and with high enantioselectivities.

Triaryl-phosphines and -phosphites bearing fluorous ponytails give high rates, good linear selectivity and good retention of catalyst in the fluorous phase during hydroformylation of alkenes in fluorous solvents.

Substitution of organic with inorganic fungicides (phosphites, Phi) does not change the efficiency fertilizer nitrogen (Nf) in winter wheat. This hypothesis was tested 2016/2017 and 2017/2018 growing seasons. A two-factorial experiment three phosphite variants (Cu–Phi, Mg–Phi, Cu/Mg) six plant protection methods (fungicides + Phi ⟶ reduced fungicide frequency phosphite). Grain yield decreased i...
