Diphenyl Phosphorazidate (DPPA) − More Than Three Decades Later
More than thirty years have already elapsed since we introduced diphenyl phosphorazidate (diphenylphosphoryl azide, DPPA, (PhO)2P(O)N3) as a reagent for organic synthesis in 1972 (Figure 1). During these years, DPPA has been found to be effective for a variety of organic reactions as a versatile synthetic reagent. It is not too much to say that DPPA has secured an established position as a reag...
متن کاملTributylstannyl Azide as Efficient Reagent in the Synthesis of Aryl
An efficient and straightforward method for one-pot synthesis of aryl azides from the corresponding amines, employing tributylstannyl azide as transfer reagent of N3 group is described. In this procedure diazotization of aryl amines occurs under mild conditions using tert-butyl nitrite (t-BuONO) and p-toluenesulfonic acid (TsOH). A variety of substituted aryl amines, with both electron-withdraw...
متن کاملUltrafast spectroscopy and computational study of the photochemistry of diphenylphosphoryl azide: direct spectroscopic observation of a singlet phosphorylnitrene.
The photochemistry of diphenylphosphoryl azide was studied by femtosecond transient absorption spectroscopy, by chemical analysis of light-induced reaction products, and by RI-CC2/TZVP and TD-B3LYP/TZVP computational methods. Theoretical methods predicted two possible mechanisms for singlet diphenylphosphorylnitrene formation from the photoexcited phosphoryl azide. (i) Energy transfer from the ...
متن کاملSome Useful Synthetic Applications of Gold's Reagent
Introduction While looking for some appropriate research projects, I had been impressed by and interested in the work of Danishefsky' and others' regarding the use of "Eschen-moser's salt" (1). During the course of a l~terature search on an industrial project, we came across an article by Gold,' which described the preparation of a rather interesting vinylogous iminium salt (2). The name assign...
متن کاملTwo Manifold Problems with Applications to Nonlinear System Identification
Recently, there has been much interest in spectral approaches to learning manifolds— so-called kernel eigenmap methods. These methods have had some successes, but their applicability is limited because they are not robust to noise. To address this limitation, we look at two-manifold problems, in which we simultaneously reconstruct two related manifolds, each representing a different view of the...
