NOVEL ALKYL PYRAZINE COMPLEXES OF LESS COMMON METALS-II

Alkyl pyrazines are found in plants and certain glands of some insects where they appear to behave as pheromones. We have initiated a project on the metal complexation of these alkyl pyrazines. We report the synthesis, elemental analysis, i.r., 1H and 13C studies of gold (III) halide complexes with 2,6-DMP (2,6-dimethyl pyrazine). A brief comparison is made with the corresponding 2,6-DMP-Pt(II) halide complex. Here, as in the case of 2,6-DMP-Pt(III) complex, metal-pyrazine bonding is evidenced through N-1 rather than N-4.
