Can u pls explain me the mechanism of this 2 reaction?

yes sir and sir pls tell me R2CuLi react with compounds like

check this https://www.masterorganicchemistry.com/2016/02/05/gilman-reagents-organocuprates-what-theyre-used-for/

first read this so you can understand how this reagent attack

after that you will be able to understand these two reaction

I have already read this sir

so still doubt?

R2CuLi attack towards less sterically hindered site

here in 1st example SN2 occur

yes sir pls tell me this reagent react with which compounds

while in 2nd conjugate addition

yes, wait

I'm explaining it giving you some examples

but sir galiman reagent do machial addition but here their is no alpha bita positions

check it

yes, simun in 2nd there is Michel addition

just like unsaturated carbonyl

actually it is soft reagent so attack on soft side

got it?

yes sir I m confused in first one

what's your confusion?

and sir what is soft and hard reagent and what is hard and soft side

have checked micheal addition notes in booklet where mentioned everything about it. it is based on HSAB principal

you if you need i can send HSAB

no sir in jam booklate their is not given this

yes sir pls send me

wait

go through this link https://www.adichemistry.com/inorganic/cochem/hsab/hard-soft-acid-base-theory.html

sir can u pls send me Michael addition from Csir net booklate

yes, I'll send you

tqq sir after I m reading it I will asked about this question further

yes, sure.

sorry net is slow this time I'll send you later

yes sir I m waiting for it

don't worry I'll send you soon😊

sir pls tell me this reagent react with compounds like

and sir pls tell me what's the picture trying to say I can't understand it

it's trying to say which compounds show cleavage of C-X bond 8n presence of Gilman reagent

this reagent is not given in the CsIR booklet

sir I m asking for Michael addition note of csir net

and the reagent react with compounds like

it react with carbonyl, epoxides etc

it is nucleophilic reagent so just like other reagent can react with carbonyl or epoxides and gives SN2

sir acid cl also react with this na

and sir what is the mechanism when this reagent react with epoxide

sir can u pls tell me this

Simun, I'm very busy this time so i couldn't reply. I'll be back with solution

yes sir I m waiting

check the reactions given by R2CuLi and examples
