Pentafulvenes are a unique class of compounds that originally attracted attention due to their propensity to display nonbenzenoid aromaticity. Subsequently, they were recognized as valuable synthons for the construction of a wide range of compounds by virtue of their ability to display multiple cycloaddition profiles. Naturally, this area of organic chemistry has experienced rapid growth over the last five decades, fueled by elegant work showcasing the unique reactivity of pentafulvenes in a plethora of cycloaddition reactions. In this Review, we have attempted to provide a systematic account of the methods for the generation of pentafulvenes, their rich and varied cycloaddition chemistry, organometallic reactions, and theoretical studies that support their versatility. Further, we have highlighted their applications in the synthesis of a variety of complex structural frameworks. It is our conviction that this Review will be useful to a wide range of chemists, and will spur further research in this promising area.

Detailed studies on hydrogen evolution by decamethylruthenocene ([Cp* 2 Ru II ]) highlighted that metallocenes are capable of photoreducing hydrogen without the need for an additionals ensitizer.E lectrochemical, gas chromatographic, and spectroscopic (UV/Vis, 1 Ha nd 13 CNMR) measurements corroborated by DFTc alculations indicated that the production of hydrogen occurs by at wo-stepp rocess. First, decamethylruthenocene hydride [Cp* 2 Ru IV (H)] + is formed in the presence of an organic acid. Subsequently, [Cp* 2 Ru IV (H)] + is reversibly reduced in ah eterolytic reaction with one-photon excitation leadingt oafirst releaseo fh y-drogen. Thereafter,t he resultant decamethylruthenocenium ion [Cp* 2 Ru III ] + is further reduced with as econd releaseo f hydrogenb yd eprotonation of am ethyl group of [Cp* 2 Ru III ] + .E xperimental and computational data show spontaneous conversion of [Cp* 2 Ru II ]t o[ Cp* 2 Ru IV (H)] + in the presence of protons. Calculations highlight that the first reductioni se ndergonic (DG 0 = 108 kJ mol À1 )a nd needs an input of energy by light for the reactiont oo ccur.T he hydricityo ft he methylp rotons of [Cp* 2 Ru II ]w as also considered.Supporting information and the ORCID identification number(s) for the author(s) of this articlecan be found under: https://doi.
