A simple and effective method for the synthesis of N,N-dichloroamines from primary amines was conducted successfully with m-CPBA as oxidant and FeCl3 as chlorine source at 0 °C. Moreover, N,N-dichloroamines could be converted into nitriles or N-chloroimines in good yields.

Selective Oxidation of 1-Tetralones to 1,2-Naphthoquinones with IBX and to 1,4-Naphthoquinones with Oxone® and 2-Iodobenzoic Acid. -The substituents on the aromatic tetralone ring have a significant effect on the product yields. Oxidation of substrates (III) to the corresponding 1,4-naphthoquinones is unsuccessful. -(REN, J.; LU, L.; XU, J.; YU, T.; ZENG*, B.-B.; Synthesis 47 (2015) 15, 2270-2280, http://dx.

The preparation of naphthoquinones by oxidation of 1-tetralone derivatives is reported. 1,2-Naphthoquinones were prepared by oxidation with IBX and 1,4-naphthoquinones were prepared by oxidation using Oxone ® and 2-iodobenzoic acid. The mechanistic pathways are also discussed.

The N-Chlorination of Primary Amines Using FeCl 3 and m-CPBA. -N,N-Dichloroamines are prepared from primary amines using m-chloroperbenzoic acid as oxidant and FeCl 3 as chlorine source. Products can be readily converted into the corresponding nitriles or N-chloroimines. -(LIU, J.; XU, J.; REN*, J.; ZENG, B.-B.; Chem. Lett. 43 (2014) 2, 190-192, http://dx.doi.org/10.
