Ald ketones

in 5th why wont ph- do 1-4 addn (conjugate addn), PhMgBr does conjugate addn

[copper niche]

RLi is a strong nucleophile

Strong nucleophiles do 1-2 addition on conjugated carbonyl

[pastel drift]

Ph- Li+ hai A

hard nucleophile

so hard center pe jayega

[cinder jay]

Huh isn't PhMgBr a strong nucleophile too

[copper niche]

Dono strong hai

[cinder jay]

but PhMgBr does 1,4 addition in this case

ch3mgbr does 1,2 tho 😭

[copper niche]

Accha

😔

Hoga koi exception

[cinder jay]

sad :(

[pastel drift]

its a soft nucleophile iirc

[cinder jay]

and Cu ki presence me always 1,4 hoti hai na with grignard

[pastel drift]
