- Bicyclo-2,5-heptadiene can be prepared in two steps from cyclopentadiene and vinyl chloride. Provide a mechanism for each step.arrow_forwardDiphenylacetylene can be synthesized by the double dehydrohalogenation of 1,2-dibromo-1,2-diphenylethene. The sequence starting from (E)-1,2-diphenylethene consists of bromination to give the dibromide, followed by dehydrohalogenation to give a vinylic bromide, then a second dehydrohalogenation to give diphenylacetylene.(a) What is the structure, including stereochemistry, of the vinylic bromide?(b) If the sequence starts with (Z)-1,2-dibromo-1,2-diphenylethene, what is (are) the structure(s) of the intermediate dibromide(s)? What is the structure of the vinylic bromide?arrow_forwardDialkyl peroxides are a family of compounds which can be explosive when heated. These explosions begin with the following bond fragmentation (which is then followed by other reaction steps). Which process best describes this fragmentation? E2 Elimination Heterolytic dissociation Homolytic dissociation Racemizationarrow_forward
- When (1-bromoethyl)cyclohexane is heated in methanol for an extended period of time, five products result: two ethers and three alkenes. Predict the products of this reaction, and propose mechanisms for their formation. Predict which of the three alkenes is the major elimination productarrow_forward3-chloro-1-butene reacts with sodium ethoxide in ethanol to produce 3-ethyoxy-1-butene. In the absence of sodium ethoxide, 3-chloro-1-butene reacts with ethanol to produce both 3-ethoxy-1-butene and 1-ethoxy-2-butene. Explain these results. Be sure to include mechanisms and structures in your explanation.arrow_forwardGive all the monobromination products of 2-methylpropane (or isobutane) in presence of heat or energy. Identify the major product and propose a mechanism leading to the formation of the major product. Provide a reaction in the termination step.arrow_forward

Write an equation for the reaction Propose a mechanism to account for the formation of butylbenzene Propose a mechanism to account for the formation of (1-methylpropyl)benzenearrow_forwardOptically pure Compound 1 undergoes a reaction at room temperature with sodium methoxide (NaOCH3) in methanol to form a single isomer of Compound 2 as shown below: 1. What are the stereochemical designations (R or S) of Compound 1 and Compound 2? 2. On the basis of the structure of Compound 2 and the information on the reaction conditions, suggest which type of mechanism Compound 1 undergoes . 3. The rate of the above reaction is determined experimentally to follow second-order kinetics. Give a fully labelled sketch of a reaction coordinate diagram for the reaction. 4. draw a mechanism on a piece of paper (using curly arrows) to show the formation of Compound 2 from Compound 1 including any activated complex. 5. If the sodium methoxide is left out of the reaction mixture, Compound 2 is formed in roughly equal amounts with another compound (Compound 3). Suggest a structure for Compound 3.
