2-(Pyridinium-1-yl)-1,1-bis(triflyl)ethanides have been used as 1,2-dipole precursors in a metal-free direct [2+2] cycloaddition reaction of alkynes. Starting from stable zwitterionic pyridinium salts, the electron deficient olefin 1,1-bis(trifluoromethylsulfonyl)ethene is generatedin situand...
Spontaneous chemical oscillations are uncovered in the uncatalyzed bromate–pyrocatechol reaction conducted in a stirred batch reactor. Phase diagrams show that the oscillatory behavior is more sensitive to the ratio of [bromate]/[pyrocatechol] than their actual concentrations. The long induction time obs...
If heated in xylene, migration of the benzyl group leads to dearomatization of the central benzene ring in a first-order reaction.doi:10.1002/chin.199010171BOLTON, R. E.MOODY, C. J.REES, C. W.WILEY‐VCH Verlag GmbHChemInform
multicomponent reactionsThe synthesis of xanthones via a multicomponent reaction of isocyanides is described for the first time. In this one-pot process, a tandem [4+1] plus [4+2] cycloaddition leads to polysubstituted 4-aminoxanthones in excellent to quantitative yields at room temperature in a...
FURTHER EVIDENCE FOR THE DIENONE-IMINE INTERMEDIATE IN THE FISCHER INDOLE SYNTHESIS: AN UNCATALYZED FISCHER REACTION UNDER MILD CONDITIONSEvidence has been presented for the transient formation of a dienone-imine intermediate in the Fischer indole synthesis analogous to the dienone intermediate found in...
