Ch16: Ethers Epoxides and Sulfides

Summary In contrast to alcohols ethers are fairly unreactive except to very strong acids such as HI or HBr This low reactivity makes them useful as solvents e g diethyl ether Et 2 O and tetrahydrofuran (THF) C 4 H 8 O Epoxides are more reactive than simple ethers due to the inherent ring strain and react with nucleophiles resulting in ring opening:

Abstract Studying seemingly simple metathesis reactions between ZnCl 2 and t BuMgCl has surprisingly revealed a much more complex chemistry involving mixed magnesium-zinc compounds that could be regarded as Mg-Zn hybrids Thus the reaction of equimolar amounts of ZnCl 2 and t BuMgCl reveals the formation of the unprecedented mixed Mg-Zn complex [(THF) 4 Mg(μ-Cl) 2 Zn(t Bu)(Cl)]
