What are Metapelitic rocks?

What are Metapelitic rocks? Metapelites are metamorphic rocks derived from clay-rich sediments includ- ing unconsolidated sediments such as mud and clay, and consolidated sedi- ments, e. g., shales, claystones and mudstones. After incipient metamorphism, all these sedimentary rocks are collectively termed argillite. What type of rock is Pelite? An aluminium-rich, Read more…

Do Gilman reagents react with ketones?

Do Gilman reagents react with ketones? Gilman reagents (organocuprates) perform two reactions that Grignard reagents (and organolithiums) do not: They perform conjugate additions to α,β unsaturated ketones. They are effective nucleophiles for SN2 reactions. What can Gilman reagents react with? Gilman Reagents Organolithium reagents react with cuprous iodide to give Read more…
