What is Silane, trimethyl-, copper complex?
The Uses of Silane, trimethyl-, copper complex
Trimethylsilylcopper is a nucleophilic silylmetal reagent useful for the regioselective preparation of allyltrimethylsilanes from allylic halides,allylic sulfonates,and allylic phosphates, participate in the following synthesis reactions: Silylcopper Reagents, Synthesis of Allylsilanes, etc.
Preparation
Trimethylsilylcopper is prepared in situ by adding 1 equiv of copper( I) iodide dissolved in dimethyl sulfide (2.5Msolution) to a vigorously stirred solution of 1 equiv of trimethylsilyllithium6 (prepared from hexamethyldisilane and methyllithium–lithium bromide complex) in HMPA at 0–5°C under argon. The reagent is used immediately in silylation reactions.
