Draw the product of the following reaction between propanoyl chloride and p-methoxynitrobenzene. Include all formal charges.
Two students are given the starting material benzoic acid and are asked to prepare benzaldehyde. The first student starts by refluxing her sample of benzoic acidin thionyl chloride in the fume hood. Upon completion of the reaction, she evaporates the thionyl chloride to isolate compound A. She treats compound A with astoichiometric amount of lithium tri-tert-butoxyaluminum hydride at –78 °C in diethyl ether, producing compound B. Adding water, she isolates her product, compoundC. The second student takes a different route....
The above reaction proceeds to yield only a single product.Draw the structure(s) of the carbocation intermediate(s), including resonance contributors, to show why this is the case.Draw the H from the addition explicitly. DO NOT draw any other hydrogens.Do not consider stereochemistry.
1. Predict the oxidation product of treating dihydronaphthalene with the reagents shown below. Only draw one enantiomer if more than one is possible. Include H'son chirality centers. (THF = tetrahydrofuran) (ABOVE)2. Alcohols can be oxidized by chromic acid derivatives. One such reagent is pyridinium chlorochromate, (C5H5NH )(ClCrO3–), commonly known as PCC. Draw theproposed (neutral) intermediate and the organic product in the oxidation of 1-butanol by PCC when carried out in an anhydrous solvent such as CH2Cl2.
