Heldmann, Dieter K. and Sauer, Jürgen (1997) Synthesis of metallated (metal equals Si, Ge, Sn) pyridazines by cycloaddition of metal substituted alkynes to 1,2,4,5-tetrazine. TETRAHEDRON LETTERS, 38 (33). pp. 5791-5794. ISSN 0040-4039
Full text not available from this repository.Abstract
MR3-substituted alkynes 2 and 3 (M = Si, Ge, Sn; R = alkyl) show high reactivity in inverse-type Diels-Alder reactions with the R-electron-deficient 1,2,4,5-tetrazine 1 in strict contrast to the corresponding carbon compounds. Kinetic data prove the huge accelerating effect of the trialkyltin substituent, offering a simple access to new heteroaromatic organotin derivatives, which can be easily transformed by standard methods of organotin chemistry.
