Synthesis Of Alkylthio Benzene Derivatives Via Simultaneous Diazotization And Nucleophilic Displacement, Abraham Alvarado, Juan D. Deleija, Jose J. Gutierrez
Chemistry Faculty Publications and Presentations
Alkylthio benzene derivatives were effectively synthesized by simultaneous diazotization of aromatic amines and nucleophilic displacement. The method is fairly general and proceeds in moderate yields. Product yields were comparable regardless of steric hindrance of the thiol or of the functional group present in the starting material. The newly developed procedure allowed for the incorporation of a tertiary alkylthio group, which cannot be easily introduced otherwise. The products were characterized by 1H NMR and 13C NMR.

Boron Fertilization Effects On Nutritive Parameters Of Alfalfa, F. M. Rouquette Jr., V. A. Haby, J. O. Fritz, M. Collins
Boron Fertilization Effects On Nutritive Parameters Of Alfalfa, F. M. Rouquette Jr., V. A. Haby, J. O. Fritz, M. Collins
IGC Proceedings (1993-2023)
With early pre-plant incorporation of limestone to raise soil pH to 6.8 to 7.0, alfalfa (Medicago sativa L.) may be grown successfully on acid, Coastal Plain, sandy loam soils. Fertility and forage quality for hay and/or grazing require alternative management of alfalfa on these Coastal Plain soils. A two-year experiment evaluated alfalfa fertilized with three rates of boron to quantify effects on nutritive entities, especially fiber components. On a whole-plant basis in year 1, only crude protein was increased (P < .05) at one of six harvest dates. In year 2, chemical analyses of leaf-stem components indicated consistent increases in crude protein of leaf fractions at each harvest (P < .05), reduction in neutral detergent fiber at three harvest dates (P < .06), and reduced lignin (P < .07) at the final harvest. Stem sections were affected by rate of boron at only the June harvest with an increase in crude protein (P < .05). Rate of boron fertilization had indirect effects on nutritive value (crude protein) by either delaying physiological maturity or enhancing nitrogen fixation in leaves, and had a direct negative effect on certain fiber components.
