An example of double reactivity in the solid state was achieved from a single binary array directed by charge-assisted hydrogen bonds assembled via mechanochemistry: [(HFu-)(Im+)] (1). The photochemical transformation of 1 occurs via a topotactic fashion with a quantitative yield followed by a second grinding-irradiation cycle. The recrystallisation of the photoproduct produces a novel hydrogen supramolecular isomer of [(rctt-H2Cbtc2-)(Im+)2] (2). Another example of the regioselective and quantitative preparation of rtct-cyclobutane isomers was obtained from the controlled isomerisation of 2 under hydrothermal conditions. Upon heating, 1 produced an unexpected hydroamination product (3) in almost quantitative yield. The stereochemistry of products 2 and 3 was confirmed by X-ray single crystal diffraction analysis.
