Fluorinated butatrienes
Ehm, Christian,Akkerman, Floris A.,Lentz, Dieter
experimental part, p. 1173 - 1181 (2011/02/16)
Major improvements in the synthesis of 1,1,4,4-tetrafluorobutatriene (1) are presented. Despite many attempts to isolate new metal complexes of 1 only an iron complex containing a ligand which is composed of a partially hydrolyzed tetrafluorobutatriene-dimer and carbon monoxide could be isolated and characterized by X-ray crystallography. Certain metal centers and solvents accelerate the decomposition of 1. First attempts to synthesize 1,1-difluorobutatriene (2) are presented which underline the major challenges of a successful synthesis of 2.
Reactions of difluorovinylidene - A super-electrophilic carbene

, p. 24 - 28 (2007/10/03)
Difluorovinylidene is the only vinylidene that could be isolated in low temperature matrices, so far. Its unusual reactivity is governed by its extreme electrophilicity and electron affinity. Thus, it not only adds CO and N2 without difficulties, but also inserts into CH4 and even H2 at temperatures below 40 K. The reaction of F2C=C: with FC≡CF clearly reveals that the formation of methylenecyclopropene proceeds in a stepwise reaction. The most striking example for the electrophilicity of F2C=C: is the thermal reaction with Xe to give a charge-transfer complex with a characteristic IR spectrum.
