Organolithium and Grignard reagents react with the readily-formed irontetracarbonylcomplexes of α,β-unsaturated amides to give γ-ketoamides in good yield acyl transfer from the metal to the β carbon of the α,β-unsaturated amide.

A test kit for the quantitative determination of narcotic drugs comprising (A) series of sealed vessels, each vessel containing a deuterium free isotopologue of a narcotic drug in exactly defined concentrations and quantities, wherein the isotopologue differs from vessel to vessel and—wherein the quantities of the isotopologue differ from vessel to vessel or are the same for all vessels; and/or (B) series of sealed vessels, each vessel containing in exactly defined concentrations and quantities the same isotopologue in quantities which differ from vessel to vessel; wherein the free isotopologues are selected from narcotic drugs; prodrugs, salts, solvates, hydrates and polymorphs and contain at least three stable isotopes selected from the group consisting of
