A simple synthetic autocatalytic replicator is capable of establishing and driving the propagation of a reaction-diffusion front within a 50 μL syringe. This replicator templates its own synthesis through a 1,3-dipolar cycloaddition reaction between a nit

A novel and facile method for direct CC acetylenic bond formation from the C=C double bond by treatment with potassium t-butoxide (t-BuOK) in N,N-dimethylformamide in the air has been found in a 9,10-bis(4-substituted styryl)anthracene series, in 4-substituted 4'-nitrostilbene series, and in 1-(p-nitrophenyl)-4-(p-substituted phenyl)-1,3-butadiene series; its scope and limitations have been examined.The ESR spectrum of the reaction against 4-diethylamino-4'-nitrostilbene was measured to identify an anion radical specied expected for explanation of the mechanism of the dehydrogention reaction.Further, cyclic voltammetric measurements of a series of stilbenes and diphenylacetylenes were carried out in connection with the abovw mechanism.In many cases, interestingly, the use of a large excess of t-BuOH brought about succeeding hydroxylation into the ortho-position of a nitro group on the benzene nucleus.The simple hydroxylation is useful for the synthesis of substituted 5-(arylethynyl)-2-nitrophenols, which are expected to function as non-linear optical materials with the corresponding non-hydroxy compounds.The ultraviolet-visible and fluorescence spectral properties were measured and discussed also with those of the related compounds.
