Question

The preparation of phosphorous ylide involves​

Answer 1

Answer:

PHOSPHONIUM YLIDES (WITTIG REAGENTS) * The phosphonium ylides or alkylidene phosphoranes, also known as Wittig reagents, can be prepared by treating tri-substituted phosphines with the alkyl halide to give phosphonium salts, which furnish the ylides upon treatment with the base. The suitable bases include NaH, NaOMe, NEt 3, BuLi etc.,

Explanation:

Answer 2

Explanation:

Phosphorus ylides are 1,2-dipolar compounds with a negative charge on the carbon atom.

Although the use of ylide substituents in main group chemistry is still in its infancy, the first examples of isolated compounds impressively demonstrate the potential of these ligands.
