## Abstract Glutacononitrile (1,3‐dicyanopropene) (2) was converted to its anion (1) by treatment with sodium hydride in tetrahydrofuran. Both ^13^C and ^1^ NMR showed that the sodium salt of 1 in THF existed in three slowly interconverting geometries (U, W and S). These geometries were present in
## Abstract 1‐Cyclohepta‐2,4,6‐trienyl‐selanes Se(C~7~H~7~)~2~ (2c), RSeC~7~H~7~ with R = Bu, ^t^Bu, Ph, 4‐FC~6~H~4~ (12a,b,c,d) were prepared by the reaction of the corresponding silanes, Si(SeMe~3~)~2~ and RSeSiMe~3~, respectively, with tropylium bromide C~7~H~7~Br. In spite of the low stabi
