Remarkable Transformation of 2,4,6-Tri-tert-butyl-1,3,5-triphosphabenzene into the 2,4,5-Tri-tert-butyl-1,3-diphosphacyclopentadienide Anion

, 2016
In an unprecedented reaction, the reduction of 2,4,6-tri-tert-butyl-1,3,5-triphosphabenzene over a potassium mirror in toluene resulted in the abstraction of P3- and generation of the 2,4,5-tri-tert-butyl-1,3-diphosphacyclopentadienide anion, P2C3But3 ...

The test of formulated-mix herbicide activity of Cyhalofop- butyl and penoxsulam active ingredients to a numbers of rice field weeds

, 2011
Weed competition becomes a major problem in low land rice. Weeds can reduce rice production up to 60-70%. Mixing herbicides is expected to obtain a broader spectrum of control of the weeds.

Herbicide options for cultivated wild rice (Zizania palustris) in California

Weed Technology
Wild rice is a high-value specialty crop in California. Weeds are an important pest issue in this crop, yet to date, only carfentrazone is registered for weed control in this crop. Herbicide field trials were conducted in 2022 and 2023 in Shasta and Yolo

Synthesis and Physical Properties of Sterically Congested Cycloalkenes, 1,2-Di-tert-butyl-3,3,5,5-tetramethylcyclopentene and 1,2-Di-tert-butyl-3,3,6,6-tetramethylcyclohexene

, 2016
Two sterically congested cycloalkenes (9 and 10), congeners of tetra-tert-butylethylene, were synthesized and characterized. Oxidation of the bicyclic 1,3-dithietane 8 with dimethyldioxirane (DMD) gave the endo,endo-disulfoxide 13, thermal isomerization ...
