Web22 apr. 2024 · 1) Iodine, being a non-polar substance, should dissolve the most in nonpolar solvents. Yet diethyl ether the best solvent for iodine. 2) Toluene and n-Hexane, both being hydrocarbons, should have similar solubilities of iodine. Yet the solubility of Iodine in Toluene almost 20 times that of n-Hexane. How do we qualitatively predict these results? Web17 feb. 2016 · The dissociative ionization of toluene initiated by a few-cycle laser pulse as a function of the carrier envelope phase (CEP) is investigated using single-shot velocity map imaging. Several ionic fragments, CH 3+, H 2+, and H 3+, originating from multiply charged toluene ions present a CEP-dependent directional emission.
Alkyl tosylates are alkylating agents because tosylate is electron-withdrawing as well as a good leaving group. Tosylate is a pseudohalide. Toluenesulfonate esters undergo nucleophilic attack or elimination. Reduction of tosylate esters gives the hydrocarbon. Thus, tosylation followed by reduction allows for the deoxygenation of alcohols. WebThe chemistry of toluene/ammonia cluster ions is dealt with in a separate report. The particular focus of this paper concerns four main themes: association of a given resolved spectrum with a ...
