A very popular and often complementary alternative to the foregoing vinyllithium chemistry is the use of lithium divinyl or diaryl cuprate species r 2 culi which also can be alkylated using primary alkyl bromides or iodides but often only in the presence of various additives typically a stabilizing phosphine ligand and the correct solvent. Vinyllithium is an organolithium compound with the formula lic 2 h 3. Cedar shakes shingles. It is a reagent in synthesis of organic compounds.

A gilman reagent is a lithium and copper diorganocopper reagent compound r 2 culi where r is an alkyl or aryl these reagents are useful because unlike related grignard reagents and organolithium reagents they react with organic halides to replace the halide group with an r group the corey house reaction such displacement reactions allow for the synthesis of complex products from.
