  • Technique for preparation of fulvalenes
    Patent number: 3941809
    Abstract: A technique for preparing a wide range of fulvalenes by a reductive procedure is described. The procedure involves reducing an organic halide to its corresponding partially hydrogenated derivative which is reacted with fluoboric acid to yield a fluoborate. Deprotonation of the fluoborate yields the desired compound. The described technique maximizes the yield and quality of fulvalenes produced and permits the preparation of thia, selena and tellura fulvalenes.
