Accepted Answer

Themissing curved arrow notationin the mechanistic step of (E)-3, 4, 5,6-tetramethylhept-3-en-2-one and (CH_3CH_2)_2CuLi is shown in the image below.Addition of Gilman reagants to Enones:Enones can go via either a 1,2 or a 1,4 addition. Most organometallic reactants prefer 1,2-addition, includingGrignard reactants. Nonetheless, the Gilman Reagent favours 1,4-addition.Thenucleophilein this reaction, the Gilman reagent (CH 3CH 2) 2CuLi, attacks the beta carbon in the enone to produce an enolate intermediate.To know more aboutmissing curved arrow notationvisit:brainly.com/question/29494780#SPJ4...
