- Hi,I need help with this chemistry question, please and thank you From the reaction between pyrrolidine and 2-methylcyclohexanone in an acid medium, enamines I and II can be formed. Describe which of the two is formed preferably and explain why?One possible side-reaction of this experiment is biphenyl, explain how it can be formed. Here is the oringial reaction bromobenzene ----->magnesium. product is benze ring with MgBr attached to ring2) Another method for the above reaction starts with 4-aminophenol hydrochloride (the conjugate acid of 4-aminophenol). The treatment of this the hydrochloride salt with sodium ethanoate (acetate) buffer produces 4-aminophenol which is then able to react with ethanoic anhydride as per our method. i. Why is 4-aminophenol hydrochloride not suitable for direct reaction with ethanoic anhydride? ii. Draw a mechanism (i.e. curly arrows) showing the deprotonation of 4-aminophenol hydrochloride by sodium ethanoate to form 4-aminophenol (the free base).
- Find the products for these two reactions. Make sure to include relevant hydrogens, deuteriums and stereohemistry.Describe how the product is purified. 4,4'-DIBROMOBIPHENYL [Biphenyl, 4,4'-dibromo-] Submitted by Robert E. Buckles and Norris G. Wheeler1. Checked by R. S. Schreiber, Wm. Bradley Reid, Jr., and Robert W. Jackson. 1. Procedure In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°. The…In this study, the researcher compared S N 2 and E2reaction rates for four substrates. Three of the substrates had a second halogen on the bposition in the molecule. This work also compared the behavior of two nucleophiles:dianion I and II. You should read the abstract and look at Scheme 1 (p. 3082) and Table 4(p. 3086). Abstract: The gas-phase reactions of benzoate and phenolate containing dianions with a series of ‚-substitutedalkyl bromides (X-CH2CH2Br, X ) H, F, Cl, Br) have been studied in a quadrupole ion trap mass spectrometer.Branching ratios between SN 2 and E2 products were measured and rate constants were determined. The‚-halogens increase both the S N 2 and E2 rates, but the effect is greater for the latter process and thereforethese substituents lead to an increase in the amount of elimination. The kinetic data for the SN 2 reactions canbe analyzed via a two-parameter, linear free-energy relationship and the results indicate that field-effects (i.e.,electron-withdrawing…

- Why cis-Ru(II)Cl2(DMSO)4 reacts with pyridine, et cetera, to give substitution of the DMSO but not the chloride ligands, but trans-Ru(II)Cl2(py)4 react with suitable Na+ and K+ salts in aqueous pyridine to afford chloride-substituted derivatives. write the reactions equations.Organotin compounds play a significant role in diverse industrial applications. They have been used as plastic stabilizers and as pesticides or fungicides. One method used to prepare simple tetraalkylstannanes is the controlled direct reaction of liquid tin(IV) chloride with highly reactive trialkylaluminum compounds, such as liquid triethylaluminum (Al(CzHs)3). 3SnCl4 + 4Al(C2H5)3 → 3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.160 L of SnCl4 (d= 2.226 g/mL) was treated with 0.346 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL). What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)? If 0.257L of tetraethylstannane (d= 1.187 g/mL) were actually isolated in this experiment, what was the percent yield?Write down the mechanisms and resulting products of the reactions below.
