Chapter 4: Action and the Pragmatic Maximed to the opposite configuration. The shape of the reaction cavity for the chiral group explained the reason why such an unusual reaction occurred. For the 1,2-bis(methoxycarbonyl)ethyl group, one of the two chiral groups was completely inverted to the opposite configuration. In the process of the i

Chapter 4: Action and the Pragmatic Maximas mixed with the product molecule. The enlarged reaction cavity in the mixed crystal accelerated the reaction. If the cavity shape is asymmetric, the produced 1-cyanoethyl group is chiral, that is, one of the . and . configurations is preferentially produced. Chirality generation was estimated from

Chapter 5: From Ground to Backgroundthe 4-cyanobutyl to1-cyanobutyl group as shown in the previous chapters. Such examples brought about an idea that the structures of the metastable or unstable reaction intermediates should be observed if the usual organic reactions proceed in the crystalline state. If the occupancy factor of the met

Chapter 6: Between Method and ,ome a new product. The reverse reaction cannot occur. The triplet carbenes are formed from the bis(2,4,6-triphenyl)diazomethane derivatives and the arylnitrenes are produced from the arylazide derivatives on exposure to UV light. The unstable carbenes and nitrenes were observed after the crystal was

Conclusion: ‘I’ll teach you differences’a variety of photoreactions of the cobaloxime complexes were observed with keeping the single crystal form. We call them “crystalline-state reactions” discriminating the usual solid-state reactions. The most important merit of the crystalline-state reactions is that we can directly “observe” the str

Crystalline-State Photoreactions: Direct Observation of Reaction Processes and Metastable Intermedicompounds, a variety of organic solid-state reactions have been studied analyzing the crystal structures of the reactant molecules in these 50 years. The postulate has been a powerful tool to understand the reaction mechanism at a rough estimate.
