Question: Drawing Ph3P=CHCH3Draw the starting reactant that would produce this alkene when treated with this reagent. Ignore inorganic byproducts. need help, will rate. thank you

Draw the product formed when Acetone (CH3-CO-CH3) reacts with a Wittig reagent - Ph3P=CH2. Draw the line angle structure of acetone, write the formula of the reagent above the arrow and draw the line angle structure of the product.

Question: OH + Ph3P=O Ph whainbat + Ph3P FIOC-Nov-COEU . CH3 Ph H3C OH CH3 EtO20 - H₃c . CO2Et EtO2C ZI The Fischer esterification reaction synthesizes an ester via a nucleophilic acyl substitution reaction. The stereochemistry of the alcohol group is unchanged as it is the alcohol oxygen that makes the nucleophilic attack.

Question: (2) (b) Draw a structure for (Ph3P)2CuBH4 that clearly shows the 3D geometry around the P, Cu and B centres. There is no need to draw out the phenyl rings; using the “Ph” abbreviation will suffice. 3. The following questions refer to Part B. Thermal Decomposition of Bis (triphenylphosphine)copper(1) Borohydride.

(Ph3P)CuBH + NaCl Wear gloves and work in the fume hood. Chloroform is an irritant which is toxic if ingested and is also potential carcinogen. Copper(I)chloride is a toxic irritant which can cause severe eye damage; therefore, it is essential to wear gloves and to remove these and wash hands) before adjusting or removing safety glasses.
