The detection of ethenimine, aka ketenimine, in Sgr B2(N-LMH) has been reported very recently:

Detection of Ketenimine (CH<sub>2</sub>CNH) in Sgr B2(N) Hot Cores
Astrophys. J. 645, L137–L140 (2006).
Three lines have been detected thus far with the 100 m GBT of which one line at 4.9 GHz probably shows partially resolved hyperfine structure. The proposed single state temperature of 65 K appears to be peculiar and may indicate non-thermal population.
