In each of seven fully controlled experiments, potted California, U.S. coast live oak trees were artificially inoculated with Phytophthora ramorum, the agent of a tree disease commonly referred to as sudden oak death. Phosphites were applied to trees using a range of application approaches either as preventive or therapeutic treatments. Soil drenches and bark application of phosphites were inef...
The mass spectrometric behavior of palladium(II) halide complexes of three types of quinolinylaminophosphonates, diethyl and dibutyl esters of [α-anilino-(quinolin-2-yl)methyl]phosphonic (L1, L2), [α-anilino-(quinolin-3-yl)methyl]phosphonic (L3, L4), and [α-(quinolin-3-ylamino)-N-benzyl]phosphonic acid (L5, L6), was investigated under positive ion electrospray ionization conditions. Each type o...
Electroless nickel plating baths have to be discarded when levels of phosphites build up and interfere with the plating process. OWMC funded research conducted at ORTECH International to determine whether phosphites could be removed from plating bath solution. The first attempt to do this by adsorption on flyash was unsuccessful. However, the use of calcium ion to precipitate calcium phosphite ...
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 ...
