Draw a pathway for the reaction of phenylboronic acid with 4-iodophenol to obtain 4-phenylphenol in the form of a catalytic cycle. EXPLAIN and STATE all complexes formed in EACH STEP by their electron counts (count how many e- are there, e.g. 18 e- or 16 e- etc.), formal oxidation states and all the reactions with mechanistic labels (i.e. oxidative addition, reductive elimination, etc.) (note the amount of base used). Be sure to EXPLAIN the catalytic cycle as to what happens...
what is the percent yield of the lab procedure below? my final weight of the product is 0.0519 g sure of the proper disposal methodl, properly Check with your laboratory insructor if you are PROCEDURE Be sure to dry the 5-mL reaction vial in the oven for at least twenty minutes.

What is the theoretical yield (in grams) and percent yield of your triphenylmethanol product in this experiment? (Weight of triphenylmethanol: 0.060g) BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...

Determine the yield limiting reagent and the theoretical yield for the following multistep synthesis from the reaction of ethyl acetoacetate. Draw the chemical complete chemical reaction and mechanism of Product C (determined to be 4-hydroxy-4 4-diphenylbutan-2-one) to Product E provided the procedure below. Procedure Step 4B [Product C to Product E] Place product [C] (0.5 g) in a 50 mL round bottomed flask, add acetone (15 mL), and concentrated HCl (2.5 mL). Boil under reflux on a water bath for...
Find %yield please the product obtained was 0.0870g In the hood, place 100 mu L of aniline in a tared 10 times 75 mm (small) test tube. Place the test cube in a small beaker or Erlenmeyer flask to avoid spillage. Stopper the cube with a cork. Now, using a Pasteur pipet, add (with swirling) 0.5 mL of water, followed by three drops of concentrated HCI. Add 10 mg of decolorizing charcoal (we use the pelletized form, called Nonrit^TM) to...
