Copper nitrate reaction with dimethyl ether

Reaction of Copper Nitrate with Dimethyl Ether. In sharp contrast to the behavior of diethyl ether, dimethyl ether shows little reactivity with copper nitrate. Dimethyl ether was condensed onto copper nitrate at —70° C. on warming to —20° C. ether evaporated to leave a pale blue solid which melted to a green oil at —12°. This oil was stable up to 50° C., and analysis showed it to be a molecular addition compound, Cu(N03)2.1.5 Me20 on treatment with water the dimethyl ether was evolved. Some decomposition of the addition compound does occur on long standing under vacuum (16),...
