S. Dua et Jh. Bowie, COLLISION-INDUCED DISSOCIATIONS OF 3 C3H3O- ISOMERS - AN INTERESTING HYDRIDE-TRANSFER REACTION, Rapid communications in mass spectrometry, 8(2), 1994, pp. 167-168
The major collision-induced fragmentation of CH2=C=C(H)(O-) occurs fol
lowing hydride transfer to form CH2=CH--C=O which then loses carbon mo
noxide to form deprotonated ethene (C2H3-).
