TLDR
Two derivatives of N6-isopentenyladenine, 3 and 4, bearing either a vinylic fluorine atom or a trifluoromethyl group, were easily synthesized from known fluorinated precursors.Abstract:
Two derivatives of N6-isopentenyladenine, 3 and 4, bearing either a vinylic fluorine atom or a trifluoromethyl group, were easily synthesized from known fluorinated precursors. Both derivatives 3 and 4 were found to be more active, as cytokinins, than the parent compounds zeatin (1) and N6-isopentenyladenine (2).

TL;DR: An enzyme activity that catalyzes conversion of N6-(Δ2-isopentenyl)adenosine (i6Ado) to adenosine was detected in cultured tobacco tissue by Paces et al. (1971) and Purification and characteristics of this enzyme in corn kernels have been studied.
