Claims41
A method for the production of a nitrosyl metal halide comprising reacting an iron triad metal dihalide selected from the group consisting of iron dihalide and cobalt dihalide, wherein the halide is selected from the group consisting of chloride, bromide, and iodide, with at least one alkali metal nitrite in a liquid in which said iron triad metal dihalide is at least partially soluble, under reaction conditions suitable for yielding said nitrosyl metal halide.
A method for the production of a nitrosyl metal halide comprising reacting an iron triad metal dihalide selected from the group consisting of iron dihalide, cobalt dihalide, and nickel dihalide, wherein the halide is selected from the group consisting of chloride, bromide, and iodide, with an alkali metal nitrite in a liquid in which said metal dihalide is at least partially soluble and in the presence of at least one elemental metal selected from the group consisting of the corresponding iron triad metal and zinc under reaction conditions suitble for yielding said nitrosyl metal halide.
