- 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(C2H5)3). 3SnCl4 + 4Al(C2H5)3 3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.230 L of SnCl4 (d = 2.226 g/mL) was treated with 0.396 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL). If 0.335 L of tetraethylstannane (d = 1.187 g/mL) were actually isolated in this experiment, what was the percent yield?Describe Suprafacial and Antarafacial Rearrangement:The molecular formula of unknown compound B is C10H16.Quantitative brominationof a 0.473-g sample of compound Brequired 48.22mL of a 0.216MBr2/CCl4to produce a color change. How many rings and pi bonds does compound Bcontain?Include any explanations/calculations to justify your answers.
- Stereoisomers of α-bromocinnamic acid: draw the reaction mechiansim with arows for the dehydrobromination of 2,3-dibromo-3-phenylpropanoic acid with ethanol and KOH to produce (Z)-α-bromocinnamic acid and (E)-α-bromocinnamic acid. Also draw the transition state for The (Z)-isomer syn-periplanar transition state and anti-periplanar transition state of the (E)-isomer.Fill in the missing reactants, reagents and products in the following reactions. Indicate stereochemistry if necessary. Unless otherwise specified, assume the reagents are in excess. PLease explaion with MUCH detail.One possible way of determining the identity of an alkene, is to let itundergo an oxidative cleavage reaction in the presence of hot basicpotassium permanganate. You are given two containers said to containdifferent alkenes. Container A is marked as cis / trans‐2‐butene andcontainer B as 2‐methyl‐1‐butene. Explain by referring to the formation ofproducts, how you would verify the identity of the alkenes.
- Using the Woodward–Hoffmann rules, predict the stereochemistry of belowreaction. a [6 + 4] thermal cycloadditionDiisopinocampheylborane (Ipc2BH) is a chiral organoborane, readily employed for the production of many asymmetric products used in total synthesis. It is a crystalline material that can be prepared as a single enantiomer via the hydroboration of two equivalents of α-pinene with borane.Explain why only one enantiomer of Ipc2BH is formed.Under basic conditions, the following substrates can undergo a [4+2] cycloaddition with regio- anddiastereo- control. Rationalize mechanistically how the reaction occurs as well as the regio- and stereochemical outcome with each base.
