Abstract:

In contrast to alkynes, their heavier ditetrel analogues called ditetrelynes E2R2 (E = Si - Pb) possess a pseudo Jahn-Teller distorted trans-bent core and two non-degenerate π bonds. This peculiar geometric and electronic structure leads to unparalleled reactivity.
It is addressed in the present lecture by unprecedented reactions of ditetrelynes with metal carbonyls and low-valent silicon compounds. Special emphasis will be given on - a) the 1,3-dipolar cycloaddition chemistry of a cobalt digermyne complex, b) the carbonyl migratory insertion chemistry into a Si≡Si triple bond, and c) the metathetical exchange of a Ge≡Ge triple bond.
