Question
Multiple Choice QuestionAn organocuprate reagent (R2CuLi)(R2CuLi) is prepared by reacting _____ equivalent(s) of a(n) _____ reagent with 0.5 equivalents of CuI.Multiple choice question.four; organolithiumone; Grignardone; organolithiumone; organosodium
Solution
The correct answer is "one; organolithium".
Here is the step by step process:
-
An organolithium reagent (R-Li) is prepared by reacting an organic halide (R-X) with lithium metal.
-
The organolithium reagent is then reacted with copper(I) iodide (CuI) to form the organocuprate reagent (R2CuLi).
The reaction is as follows:
R-Li + CuI → R2CuLi
This reaction only requires one equivalent of the organolithium reagent for every 0.5 equivalents of CuI, hence the answer is "one; organolithium".
