Question: This man's military was first led by Saint Arnaud, and his advisors included the dukes of Persigny and Morny. He was satirized in a work plagiarized to form The Protocols of the Elders of Zion, Maurice Joly's Dialogue in Hell Between Machiavelli and Montesquieu. His rule saw a boom in railway construction and the implementation of Baron Haussmann's plan to renovate the streets of Paris. He assisted Victor Emmanuel II against Franz Joseph at Solferino and he was able to briefly annex Mexico under Maximilian, but he was defeated and captured by Moltke at Sedan, ending the Franco-Prussian War. For 10 points, name this French emperor, the nephew of his namesake.

Other works by this man include one written with Alfred North Whitehead, in which he explained the whole of mathematics in terms of logical expressions. For 10 points, name this modern British philosopher who wrote Principia Mathematica.

Answer: Social Science


Question: One reactant for this reaction is best prepared by an S N 2 nucleophilic addition of a triphenyl compound, followed by elimination of the hydrogen halide by an organolithium reagent. This reaction itself proceeds through a rather unique intermediate formed when the pi electron from the reagents carbon-oxygen double bond migrates to the positively charged pole of one reactant; this intermediate is called a an oxaphosphetane, from which a triphenyl oxide is eliminated to complete the reaction. The aforementioned positively charged pole is on phosphorous because the aforementioned prepared reactant is a phosphorous ylide. For ten points, name this reaction that produces selectively double-bonded alkenes from aldehydes and phosphorous ylides and that is named for the German 1979 Chemistry Nobel winner.
