or this
"Yes, phenyl magnesium bromide (PhMgBr), also known as phenylmagnesium bromide or Grignard reagent, can be used to attach a phenyl group to the ketone group in N-Phenethyl-4-piperidinone (NPP) through a Grignard reaction.
In this reaction, phenyl magnesium bromide acts as a nucleophile, attacking the electrophilic carbonyl carbon of the ketone group in NPP. This results in the formation of a carbon-carbon bond between the phenyl group and the ketone, yielding a new compound with the phenyl group attached."
im gonna be real with you, i didnt find much of anything on other sites so i used AI for this. someone make sure im right. hope this could do something for u
