I need help on this quétion! 3. Synthesize 1,1-diphenylethylene, starting from benzene. You may use any reagents to complete the synthesis. (10pts.) Retrosynthesis may be helpful.
4. Propose an efficient synthesis of the molecule below starting with benzene. You can use any other reagents you want. NOTE: Some reactions produce ortho- and para-products. It is allowable to just take ONE of the products and use it in the next synthesis or claim it as the final product (we assume that ortho- and para-products can be separated). (3 points) CH2CH2CH Br
Problem #3 Show how you would synthesize ethyl benzoate in good yield starting from benzene. You may use any other reagent necessary
Design a synthesis for 1-bromo-4-methyl-2-nitrobenzene using benzene as the starting material. You can handwrite everything. Please show the structures of the intermediates after each step as well as the reagents used. (NOTE: you can NOT use Friedel-Craft alkylation after Nitration.) ALSO, Professor said: ch3Br/FeBr3 --> Br/FeBr2 --> HNO3/H2SO4 OR Br2/FeBr2 -> CheCL/ALCL3 -> HNO3/H2SO4 would NOT work. Hint: need protecting group

Problem #3 Show how you would synthesize the compound represented in the Fischer projection below starting from acetylene. You may use any other reagent necessary. HC-OH HC-OH Extra Credit When treated with hydrogen and a platinum catalyst, an unknown compound X absorbs 5 equivalents of hydrogen to give 7-butylcyclohexane. Treatment of X with an excess of ozone, followed by dimethyl sulfide and water, gives the products shown below. Propose a structure for X.
