Explain why organocopper and organocadmium reagents react with less reactive acid chlorides even though they do not reacts with more reactive ketones. |
Answer» Solution :`R_2 CULI`(and `Ar_2 CuLi`) and `R_2 Cd` and `Ar_2 Cd` do not REACT by the typical nucleophilic addition `(NA)` reaction of an  FORMING an acylium-like ion with greater `+ delta` charge on the carbon. This strong electrophilic ion can form a bond even with the weak nucleophlic `R` of `R_2 CuLi` or `R_2 Cd`. B
