Question

Show the reaction that produces phosphorus ylide using the correct alkyl halide.

Answer 1

[AI-generated answer — Bot GPT 3.5]

Phosphorus ylide is typically prepared by reacting a primary alkyl halide with triphenylphosphine (Ph3P) in the presence of a strong base, such as sodium hydride (NaH).

One example of this reaction is the synthesis of phosphorus ylide from the primary alkyl halide ethyl bromide:

2 Ph3P + 3 NaH + CH3CH2Br → Ph3P=CH2 + Ph3PH + NaBr + NaBr + NaH2PCH3

In this reaction, the primary alkyl halide ethyl bromide reacts with triphenylphosphine and sodium hydride to form phosphorus ylide (Ph3P=CH2) along with other byproducts.
