A new protocol is described for the conversion of heteroarene N-oxides to
heteroarylphosphonates through in situ activation with bromotrichloromethane. The N …

A highly efficient synthesis reaction of carboxylic anhydrides catalyzed by
triphenylphosphine oxide is described for the quick synthesis of a range of symmetric …

NaBH4, CH3CO2H, Pd/C has been described as an effective reagent system to
hydrogenate alkenes. Here, we show that the hydrogenation occurs chemoselectively …

Organic synthetic research laboratories generate a large amount of waste. Some of the
waste is the silica gel used as the stationary phase in column chromatographic separations …

The last decade has seen a huge growth in the construction of chiral systems to expand the
scope of chiroptical applications. Dependence of chiroptical response on molecular …

Symmetric cinnamic anhydrides were prepared by the reactions of cinnamic acid substrates
with 6-chloro-2, 4-dimethoxy-sec-triazine. The reactions were performed at room …

In search of new thermotropic, photoswitchable materials, a number of 4′-alkoxy-4-(ω-
cinnamoylalkoxy) azobenzenes were prepared. The synthetic procedure included O …

Activated alkenes such as cinnamates and chalcones can easily be converted to 2, 3-
dideuterio-arylpropionates and dideuteriochalcones, respectively, by the action of NaBD4 …

Fluorinated nucleosides are very important for increased biological and chemical stability of
organ fluorine compounds. Synthesis of (1H)-8-trifluloromethyl-2-methyl-4-quinazolinone 3 …

In certain countries, many of the reagents used to transform carboxylic acids to acyl halides
such as phosphorus trichloride, phosphorus tribromide, phosphorus pentachloride …
